How to Stop Annoying People Calling You

For some reason, someone from the Australian Stock Report rang me trying to sell me investment advice. The investment advice costs about $1000 per year, which is a rip off. Anyway, I tried to argue with this guy, but he didn't really address what I said. He just talked about a bunch of unrelated things. I suppose the logical thing for me to do would be to just hang up, but I suppose one of my personality flaws is that I am too polite. He said he was going to call me in a few days.

I have an app on my phone called Truecaller that I used to block his number. This is a great app. The problem is that marketers can easily turn off caller ID thereby making the caller show up as "private number." The Truecaller app has an option to block all private numbers, which I activated for a while.

The only problem is that my mother's phone, when she calls me, shows up as a private number. I've tried very hard to turn this off on my mother's phone, but nothing has worked, so unless I want to block my mother, I need to accept private calls, which means I am vulnerable to spammers and marketers.

What I will do when I receive a private number is simply pick up the phone but say nothing. I will wait for the other person to speak. If it's a voice I recognise, I'll keep talking. If it's a voice I don't recognise, I'll just hang up.

Khmer Font on Sony Xperia Z

If you are a Cambodian person using an Android device, I highly recommend Khmer Standard Keyboard (or try Khmer Standard Keyboard Small Screen for mobile). Once you install one of these apps, go to Settings >Language & input > Default and enter Khmer Standard Keyboard as the default keyboard. The Khmer keyboard should show up whenever you type. The keyboard has a button on the bottom-left that allows you to toggle from an English keyboard to a Khmer keyboard.

If you go to a Khmer website like rfa.org/khmer, you can see Khmer text rendered on the website and, if you are Cambodian, you can read in Khmer on this site. This works for my Firefox browser on my desktop, the Nexus 5, and the Samsung Galaxy S4, as well as many other devices.

However, when you go to rfa.org/khmer using a Sony Xperia Z, the Khmer text does not show up!

This was extremely frustrating. I spent many hours trying to get Khmer font to show up but nothing worked. All the websites kept telling me to root the phone, but rooting the phone can void your warrantly, so it's best not to do that.

I finally got around the problem by installing Firefox for Android and then searching for add-ons and then installing Khmer Fonts Package. This seemed to fix everything up. Khmer text still does not appear on Chrome browser and other apps but it does show up in the Firefox browser, which means you can do a Google search in Khmer and read Khmer websites.

There are a few other apps that seem to show Khmer text on the Xperia Z, e.g. Khmer SMS, Kohsantepheap Daily, and even Google Translate.

Why I Got a Red Nexus 5

About a month ago I purchased a red Nexus 5. I used to have a Sony Xperia Z. Some people have asked me why I purchased a new phone. Below are my reasons.

1. Faster processor

The Xperia Z has a Snapdragon S4 Pro processor whereas the Nexus 5 has the faster Snapdragon 800 processor. The Nexus 5 is approximately 80% faster according to Antutu benchmarks.

2. There were problems with the camera on my Xperia Z

For some reason, dust particles appeared in the lenses of my Xperia Z. It turned out that this was a common problem on Xperia Z phones. Luckily for me when I purchased the phone from Kogan, it was still under the one-year warranty. I sent the phone to Kogan for repair and they gave me a brand new Xperia Z. However, it took them about two months to send the new phone to me and during that time I had to use the backup phone, i.e. the Kogan Dual-Core Smartphone, which is a horrendously slow phone compared to the Xperia Z. So I simply decided to buy a Nexus 5. It turns out that when my Nexus 5 arrived in the mail, the new Xperia Z came at the same time.

3. My mother can use the Xperia Z

My mother currently uses the Samsung Galaxy Y and she constantly complains about how bad this phone is. She says she will buy a new phone but hasn't done much about it yet. My intention is that she can use my Xperia Z, although to date she hasn't accepted it yet. Perhaps she is looking for a smaller phone.

4. The Nexus 5 is cheap and I had the money

Whenever I arrive home, I empty any coins in a jar in my bedroom. When my Xperia Z was being repaired, I decided to collect all the coins in this jar and take it to the bank to deposit the money. It turned out that I had enough money to buy a new Nexus 5, so why not? I saved up for it and I haven't gone into debt and I have not gone on a phone plan. It is unlocked and off-contract, so there are no obligations on me.

Why is Quickflix not on Google Play?

I have a Quickflix subscription and was going to stream Quickflix movies on my Android TV, but then I looked through Quickflix's devices and it looks like the Quickflix app is available on every single app store other than Google Play. Now I will have to keep borrowing DVDs from them. I'm tempted to just cancel my subscription and just stream over Google Play Movies. The only thing stopping me from streaming is the fact that DVDs from Quickflix are about $3 per movie, which is cheaper than most streaming movies from Google. Quickflix should understand that because Android runs on 80% of all smartphones and 55% of all tablets, they are missing out on a large number of customers by ignoring Android.

Kogan Agora Mini 8 Dual Core Tablet - Antutu Benchmarks

I purchased this tablet from Kogan for $120 when it was available. It was quickly sold out afterwards. I purchased it for my mother. The Antutu benchmarks show that this tablet is quite fast. Not as fast as the Galaxy Note 3 but about the same as the Nexus 4. It is interesting to note that the Kogan dual core tablets are much faster than the Kogan dual core smartphones (the Kogan Agora 5) even though both are advertised as dual core. It's not just the number of cores that matter but the quality of those cores.

Khmer translator for Android with Khmer fonts

I have Khmer parents who don't speak English well. My Khmer is not as great ad my English, so communicating with them has always been difficult.

When I learned that Google Translate would now support Khmer, I celebrated because now I can use Google Translate to communicate with my parents.

Unfortunately, when I install Google Translate on my Android phone, the Khmer translation shows up using the Roman alphabet because Google Translate does not support Khmer text. This is a bummer since it means I will mot be able to show my parents the Khmer text. They cannot read the Roman alphabet well.

This problem was fixed simply by installing another app from the Google Play store called Instalator. This app is powered by Google Translate but in versions of Android greater than 4.0 it supports Khmer text. It is perfect.

Cheap iPhone will turn Apple into Samsung

Apple creates the iPhone 5 for $200 and sells it for $700. Google, on the other hand, makes zero or little profit on its Nexus devices (Nexus 4, Nexus 7, and Nexus 10).

Some people do not understand Google's philosophy, citing the fact that Google ads are found on Apple phones as well. The best way to understand Google's plan is to imagine what the world would look like if Googlr never invented Android and Apple controlled the entire smartphone market. Apple would make its iPhones for $200 and because they can they will charge $2000 for it to maximise profits. Because the price is so high, they will not sell much phones but because there profit margin on each phone will be so high, Apple is happy. Google makes money off advertising. If smartphones were all $2000 thanks to lack of competition as a result of monopoly, hardly anyone will use smartphones and therefore not many people would look at Google's ads and Google would not make much money. By creating Android, giving it away for free, and producing high-quality and cheap Nexus and Chromebook devices, Google is able to put pressure on Apple to bring its prices down and get the iPhone into more people's hands. Apple is content with selling fewer phones buy making high profit margins on each, explaining why Apple takes in 80% of smart phones profits even though 80% of smartphones run on Android.

The plan is working, and Apple is giving in. Apple will soon release a cheap plastic iPhone in an attempt to compete with Android at the lower end. Regardless of whether the cheap iPhone increases sales of Apple devices and steals market share from Android, it does not matter since Google ads are on Apple devices. A cheap iPhone will only dilute the Apple brand and transition Apple from a boutique low-volume high-margin company into a commodity mass-manufacturing, high-volume low-margin company. In other words, Apple will become Samsung.

The Key Difference Between Android and iOS

With the latest iOS 7 update, Apple phones look almost exactly like Android phones. According to Know Your Mobile, iOS and Android have copied each other to the point that they are indistinguishable.

Given that Google and Apple are both Silicon Valley tech firms, it is likely that engineers who work at Google will also one day work in Apple and vice versa. Engineers moving around ensure similar ideas are spread. Of course Google and Apple will copy each other.

While I agree that the two operating systems have similar appearances, there are still key differences between the two operating systems. For one, Google is primarily a software company that makes 93% of its revenue from advertising. They Google produce a phone, tablet, or computer, e.g. the Nexus 7, they make no profit on the product, aiming instead to move the market forward, get the device into more people's hands, and make money off advertising. Apple, on the other hand, makes most of its money off the hardware, e.g. making the iPhone 5 for $200 and selling it for around $700 to $800.

Reasons Behind the Decline of the PC

There is a lot being side nowadays about the decline of the PC as sales of tablets and smartphones boom. I still find the PC to be useful mainly because then functionality of most programs and websites on a bigger screen is enhanced significantly. Furthermore, typing on a physical keyboard is faster than a touchscreen keyboard because the touchscreen is smaller, meaning you need to use your use your thumbs to type, and on a large tablet the fact that there is no tactile feedback hampers the efficiency of touch typing. I can type quickly on a tablet, but not as fast as on a physical keyboard.

Another reason why I like to use a PC is because it is more ergonomic (see Are tablet ergonomics a pain in the neck?). Using a tablet for long periods of time causes your neck to move down and forward because you typically hold the tablet (or smartphone) down and lean down to look at it. A PC monitor, on the other hand, sits vertically in front of you, meaning it is safe.

So why do statistics show the PC is in decline? One reason, I think, is because many people already have PCs. PCs are necessary for email, banking, job hunting, and so forth. Because everyone already has a PC, not many people feel a need to buy another. They will keep it until it breaks. Not many people have smartphones or tablets, but that is changing. Many people are switching from features to smartphones and many are buying tablets.

However, just as many people are satisfied with their PCs and don't bother upgrading to the latest Alienware, I believe the smartphone market is not immune to consumers sticking to their old phones because it is good enough and not worth the upgrade. Many Apple users seem to stick with the iPhone 4 rather than upgrade to the 5 and I see many Samsung users sticking to their Galaxy S3 or S2.

One factor working in the smartphone's favour is that the smartphone is a public device. I carry my smartphone around with me and many people see me with my smartphone, so if I were very sensitive about other people's opinions of me, I will buy a beautiful and powerful smartphone to show others that I am stylish but also technologically sophisticated. The PC and tablet, on the other hand, stays at home, so getting something good enough for the lowest cost is the priority.

Many people carry tablets around, e.g. to play games or swatch movies on the train, but I only ever keep my Nexus 7 at home. I normally don't carry anything with me other than a phone, keys, and a wallet. I find it inconvenient to carry a bag or briefcase, and with everything done electronically nowadays, I think it is unnecessary.

To me, a tablet and desktop computer are similar in that they are devices used at home that offer more screen size than the smartphone. At home I rarely use the smartphone because I prefer the bigger screen on a tablet, and if I need a physical keyboard I use the PC.

PC software tends to offer more functionality than the tablet, but not by much, and although I prefer a physical keyboard, many people may not care, and if this is the case many people may find that they can save money by doing without a $500 PC and instead use a cheaper tablet. Decent tablets like the Nexus 7 cost around $200 to $300. You can check email, Facebook, do internet banking, pay bills, and job hunt on a tablet. You don't need a PC. Even if you do need a physical keyboard, you can simply buy a $50 Bluetooth keyboard to pair a $200 Android tablet, and you effectively have a laptop that costs less than most PCs (PCs typically cost around $500 or more).

All these factors I think explain the decline in PC sales. PC manufacturers should just switch and focus on making more phones and tablets.

Stock Android is Overrated

http://www.theage.com.au/digital-life/mobiles/i-tried-the-android-now-give-me-back-my-iphone-20130719-2q92e.html

The opinion piece above from The Age has boiled my blood. I feel I need to address it. The piece claims that Android phones are bad because they are not pure Android phones and even if they are pure Android phones.

I currently have both a Nexus 7 running stock Android and a Sony Xperia Z running Android with Sony refinement. I find the Xperia Z to be much better than stock Android mainly because of added functionality, e.g. small apps and Bravia Engine. Many people actually want to pay more money for more features.

The Nexus devices make sense because they are cheap. The Xperia Z costs about $600 off contract compared to about $330 for the Nexus 4. It makes sense to pay less for something with lesser functionality and features. But $600 for a Google Play Edition Galaxy S4, which is the same price as the normal GS4? No thanks. The iPhone 5 is even worse, as you are paying $800 for an operating system with even less functionality and features than stock Android.

The Importance of Android

The Android operating was invented in 2003 as a camera operating system. It was purchased by Google shortly after and the operating system was modified slightly for use on touchscreen smartphones.

The Apple iPhone was released in 2007 and quickly dominated the touchscreen smartphone market previously dominated by Microsoft's Palm devices. The Apple iPad was then released, also dominated the tablet market, quickly outselling Microsoft's Tablet PCs.

Android started slowly but its growth was explosive. Today Android is used on 70% of all smartphones. It is a free and open source operating system used by numerous manufacturers.

One of the benefits of Android is that the manufacturers who use it are faced with greater competitive pressure, leading to greater value for money for the consumer. If you owned an iPhone 4S and wanted to upgrade to get a faster phone, so you search online and realise that the fastest phone on the market today is the Samsung Galaxy S4. You want to buy it but realise that if you do, you will not be able to transfer your music on iTunes, your apps on the Apple App Store, and so forth to the Galaxy S4 because it uses a Android. So you reluctantly buy an iPhone 5, a phone that is more expensive than the Galaxy S4 but two times slower. This problem exists because you are trapped in the Apple ecosystem. But what if you were in the Android ecosystem and used, say, a Samsung Galaxy S3? Then your upgrade choices are infinite. You buy a phone from HTC, Sony, Motorola, LG, Huawei, Asus, HP, Oppo, and many more. You can buy a phone to suit your preferences and tastes, and if any company wants to rip you off, simply move to another one. You cannot do that with Apple. You are stuck with one company that has no incentive to offer you a better product for a lower price.

Although it is difficult to move from Apple to Android, it all depends on how invested you are in the system. If Apple takes advantage of its customers too much, they may get so angry they will be willing to switch to Android regardless of the costs, so the existence of Android does put pressure on Apple as well as Android partners.

My Experience with the Sony Xperia Z

For years, Sony Ericsson has made bland and boring phones while Apple and Samsung dominated the smartphone market to create an effective duopoly.

Sony has cut ties with Ericsson and wanted to make a phone that signalled to the world that Sony was serious about smartphones. The Sony Xperia Z was born.

I've had the Sony Xperia Z for a few days now and overall I can say that I am very happy with the phone. I purchased it online via Kogan and had to wait about two weeks before it was sent to my house. I love buying goods online because of cheapness, but it is terribly difficult waiting for a phone that I really desired. Nearly every day while waiting for the phone, I went on YouTube and searched for the latest videos on the phone. This kept me interested as I waited. I absolutely loved Sony's advertising for this phone.

Battery

My old phone was the HTC Desire HD. I've had this for about two years and it has served me well. The main problem with the Desire HD is the battery life. The phone's battery capacity is around 1230 mAh (compared to 2330 on the Xperia Z). I would charge the phone overnight, use it on the train when commuting to work, and use it intermittently for email, messaging, and calling throughout the day. By around two in the afternoon, the phone would be dead! The battery was that bad. I was able to partially fix this problem by getting a $2 USB to micro-USB connector from eBay and charging the phone at work from my computer. This was also useful because it allowed me to easily transfer files from work to home if I wanted to. I didn't need to carry around a USB flash drive. I could live with the Desire HD's poor battery life, but I preferred a phone that lasted for a whole day, at least.

The Xperia Z's battery life, I have found, is phenomenal. I charged it overnight and, when using it normally I have found that the battery is around 60 to 70 per cent full by the time I get out of work. It easily lasts the whole day with normal use and will probably last two days as well. The Xperia Z's 2330 mAh is nothing revolutionary, especially compared to the Samsung Galaxy S4's 2600 mAh battery and the Samsung Galaxy Note 2's massive 3100 mAh battery. However, the Xperia Z comes with a built-in power management software called Stamina Mode that automatically turns off power-intensive features like mobile data. Stamina Mode is customizable, so you can specify which programs are not affected by it. For example, if you use Whatsapp or Facebook Messenger to keep in contact with family and friends, you can customise Stamina Mode to ignore these apps.

Design

The killer feature of the Xperia Z is its aesthetics. It is a beautiful phone, a work of art. While the Samsung Galaxy S4, I am sure, is technologically superior, its design is similar to the S3 and is getting boring. The new Blackberry Z10 looks like an iPhone 5 with a plastic back. The LG Optimus G Pro is starting to look like there Galaxy phones as well. The Xperia Z, on the other hand, does away with curved designs and opts for a minimalistic thin and sleek black slab with sharp edges, symmetry, and shiny, reflective glass. Whenever I take this phone out of my pocket at work or lay it down on a table, just about everyone says, "wow!" "whoah!" or something similar, and typically want to touch it and play with it. The phone comes in black, white, and purple. Black is best.

The Xperia Z is not as thin as the iPhone 5, but the two are very similar, and to the naked eye the Xperia Z looks slimmer and better proportioned because it is wider. The width and tallness of the Xperia accentuate its thinness. The iPhone 5 is simply a taller and thinner version of the 4S. In their attempt to maintain better one-handed operation, the iPhone 5 looks too tall and anorexic. It is a feminine and emasculating phone compared to the manly Xperia Z. The iPhone 5 has a really small 1440 mAh battery, which is pathetic, but the iPhone has a blurrier display compared to the Xperia Z, so its power consumption should be lower.

I am using my Nexus 7 tablet to write this blog, so the pictures of the Xperia Z I have posted here use the Nexus 7's low-resolution front-facing camera. Unfortunately the Nexus 7 has no rear camera.

Another issue with the phone is that it attracts fingerprints and dust like a magnet attracting metal. Be prepared to wipe it all the time.

Waterproofing

The Xperia Z is waterproof up to one metre. This means you cannot go swimming or scuba diving but you can use it in the shower or bath tub. The waterproofing is excellent because you never know when someone will push you into a swimming pool or lake. You may also drop your phone into the toilet. I take my phone into the shower with me and place it in the shampoo rack. When people call me while I am in the shower, I can tall to them, and theoretically I could Skype people while in the shower as well, but I am hesitant to try this.

Taking the phone into the shower also allows me to clean the glass panels of the phone to remove fingerprints.

That being said, the downside of waterproofing is that all ports, such as the micro-USB port and micro-SD port, have plastic flaps covering them, and you have to constantly detach and reattach these flaps if you want to charge or even put headphones into the phone. I will be getting a charging dock for the phone, so charging is not an issue. If you are into music, you will probably need to invest in expensive NFC-enabled wireless headphones. That being said, I am willing to tolerate this I'm order to get waterproofing.

Comfort
 
Although the Xperia Z is a beautiful phone, it is not comfortable to hold. My old HTC Desire HD had a rounded aluminium back that fitted well into the hand. Likewise, my Nexus 7 has a curved rubber back that feels really nice. The Xperia Z, on the other hand, has sharp jagged edges and flat glass surfaces, which feels uncomfortable compared to the Nexus and HTC. Once again, I'm willing to tolerate this, but others may not.

Conclusion

Much was said about this phone's poor colour contrast and viewing angles. I can attest that the viewing angles on this phone are far from perfect, but who looks at a phone screen on an angle? My experience is that the display is fine. The fact that it is Full HD, 1080p is a plus. It makes images and text crisp and clean. I read a lot on my phone, so high pixel density and big screens are non-negotiable.

My Experience with the eCoffeeCard App

I love my coffee. At some coffee stores I visit, there are loyalty cards where you can get a free coffee if you buy, say, 10 coffees. However, for one area I go to, they have encouraged their buyers to use eCoffeeCard, a smartphone app that keeps track of how much coffee you've had and notifies you when you're due for a free one.

I installed this app on my Android phone and used it for a while. My experiences have been negative.

Technology is supposed to make life simpler and easier. It is supposed to make you more productive. I have found that eCoffeeCard has done the opposite.

Normally when I pay for coffee, I use cash, and if there is a loyalty card, I hand this card with the cash and the barista signs the card or punches a hole in it. The barista then hands the change and card back to me. It's quite simple.

However, with eCoffeeCard, I have to pay separately with cash, then I have to take my phone out of my pocket, I have to turn it on, search for the app icon, wait for the app to load, and then I have to scan the QR barcode, and then wait for the app to recognise the barcode. Using the smartphone is significantly slower!

Normally when I buy coffee, there is a queue, and being slow means you hold everyone up.

I don't know what the solution is. Perhaps Google Glass will fix everything because you will only have to look at the barcode rather than bother with taking out your phone, etc.

First thoughts on the Samsung GALAXY S4

The Samsung Galaxy S4 (or Samsung Galaxy S IV) was released today. It was released in New York, which meant that here in Australia it was released at around nine or ten in the morning, which coincided with when I was at work. I got out of work at eleven today but missed the opportunity to watch the Samsung presentation live on YouTube.

The Galaxy S4 is nothing surprising. It pretty much looked exactly like the leaked pictures. The hardware specifications are what were expected. It has a five-inch super AMOLED display with full HD, 1080p at 440ppi. The display size and pixel density matches phones like the Xperia Z and HTC One but what is great about Samsung phones are the fact they use AMOLED displays rather than conventional IPS LCD displays. AMOLED displays give deeper blacks and more vivid and bright colours. Some people do not like th vividness of AMOLED displays, saying it is unrealistic. It's a matter of preference which one you prefer, but I prefer AMOLED.

The Galaxy S4 has an unprecedented Exynos 8-core processor. The octacore processor has four performance cores and four economy cores. When performing power-intensive tasks like gaming or watching videos, the performance cores are used whereas the economy cores are used when you are engaged in mundane tasks like web browsing. Along with the 2 GB of RAM, this allows the S4 to achieve an unprecedented 26,000 score on the AnTuTu benchmark, which is 6,000 higher than the runner up HTC Buttery's 20,000 score. This makes the Galaxy S4 the fastest and most powerful smartphone yet.

There are numerous other features on the S4, far too much to digest in this blog post. Many people claim that these features are not "proper innovation," or evolutionary rather than revolutionary features. But this is subjective. I happen to believe the octacore processor and AMOLED screen are highly innovative, but others may not think so. Many believe Apple's first smartphone, with touchscreen-only input and apps was innovative, but closer inspection reveals they are evolutions of Microsoft handheld devices like the Palm Pilot. Apple simply improved the specs and marketed the product very well.

In my opinion, the Galaxy S4 is technologically superior to any other phone on the market today. Where the S4 is criticized heavily is in the plastic material is uses for its body. Samsung have good reasons for using plastic. For one, it absorbs shock better, which means dropping it will damage it less compared to, say, a glass phone like the fragile Nexus 4. Metal phones, such as the iPhone 5 or HTC One, tend to scratch easily. Most people, when they buy a metal or glass phone, put a plastic case on it anyway for the very reason that they don't want to damage the metal or glass. Premium material is only a concern for those with so much money that, if they crack a glass phone or scratch a metal phone, they can simply afford to buy another one. Many people, when criticizing Samsung phones, refer to the "build quality." I hate it when people use this term because plastic Samsung phones don't break. The plastic actually improves its build quality. Instead of using the term "build quality," we should call it what it is and use the term "snob appeal." Samsung's plastic phones are technologically superior to any other phone out there, but lack snob appeal because plastic is perceived to be cheap and nasty.

That said, I do not mind owning a nice-looking phone. The benefit of Android is variety. For those who want glass, there is the Sony Xperia Z, which is by far the prettiest phone yet. For those who want aluminum, get the HTC One. For those who want value for money, get the Nexus 4.

Kogan Agora 10" Dual Core Tablet

Today I visited my father's house and noticed that my five-year-old half-sister held a 10-inch tablet in her hands. I asked my father about the tablet and he notified me that he had purchased two 10-inch Android tablets from online retailer Kogan.

Since one of her friends purchased a Sony tablet, my half-sister has been wanting a tablet for herself. I remember when we visited the shopping mall, she would say to her father, "I want an iPad!" and then point to a Samsung Galaxy Tab. It's not good to reward bad behaviour, but learning how to use a tablet can have educational benefits and can allow the child to familiarise herself or himself with the latest technology. Not to mention that fact that nothing mutes a loud and reckless child as effectively as a tablet PC.

In my opinion, Apple's main innovation is in its marketing. Their marketing and brand recognition is so strong that many children (and even most uninformed adults) refer to all tablets as iPads, regardless of whether they powered by the Android or Windows operating systems or whether it is made by a company other than Apple, e.g. Samsung, HTC, Sony, Motorola, or even Microsoft. But given that the latest iPad 4 would cost around $600, it just seemed stupid buying an iPad 4 for a child when the child would likely drop, break, or spill food on the device.

My cousin, thinking that she was saving hundreds of dollars by not buying the latest iPad 4, purchased instead an iPad 2 for $400. Given that it is an iPad 2, it has a low-resolution display (NOT the iPad 4's high-resolution 264ppi Retina display) and it only had a measly 0.5 GB RAM and used an ancient and weak 0.8 Ghz single-core A5 CPU. Why would you spend $400 on an iPad 2 with ancient technology when you can spend less than half that much ($180) and get a Kogan Agora 10" Dual-Core Tablet? The Kogan Agora tablet is more than two times cheaper than the iPad 2 yet also has a dual-core processor, has two times more RAM, and has a bigger battery.

That being said, the Kogan Agora 10" is not the best of the best. I would argue that the best tablets out now are the Nexus 7, Nexus 10, iPad 4, and Asus Transformer Prime. But these tablets are generally quite expensive whereas the Kogan Agora 10" is $180 whereas the smaller 8-inch Kogan Agora Dual Core Tablet is only $120. The Kogan Agora 10" also has a respectable 1 GB RAM, which is equal to the amount of RAM in the iPad 4. When I looked at the screen of the Kogan tablet, I noticed that the display was pixellated and blurry compared to the crispness of the iPad 4 and the Nexus 7. Nevertheless, for a $180 tablet, what do you expect? For most people, the low-resolution 132ppi display on the Kogan Agora tablet it is not a huge issue. It is approximately equal to that of the iPad 2. If you want high-resolution on your tablet, you'll need to pay more. The iPad 4 has an impressive pixel density of 264ppi Retina display but will cost you $600. The Google Samsung Nexus 10, however, has an even better pixel density of 300ppi and will cost you $500.

How is the battery? According to Kogan's website, the Agora 10" Dual Core has 8000 mAh. The website does not give the actual battery life of the tablet in hours, and I was not able to test it given the children were playing on it. Nevertheless, the iPad 2 has a 6,944 mAh battery and goes for about 10 hours, whereas the new iPad 4 has a 11,666 mAh battery, which is roughly 70% larger, yet still goes for about 10 hours as well given that the iPad 4 has a high-resolution Retina display and dual-core CPU, it consumed much more power. Given that the Kogan Agora has a dual-core CPU like the iPad 4 but has a low-resolution display like the iPad 2, my rough guess is that battery life will be around 10 hours as well.

I went into the Kogan Agora's browser and also played some Angry Birds to see if the tablet could handle it. It seemed quick and responsive, so it is likely that the dual-core CPU is doing its job. The kids installed various games on the tablet and played them. There seemed to be no issues with performance. The Kogan Agora also runs the latest version of Android, i.e. Jelly Bean, which is supposedly much faster than previous Android versions. All in all, I was impressed. When they carry it around with them, the children keep referring to the tablet as the "iPad," and I keep telling them, "it's a Kogan!" but they don't seem to understand.

Given that I am used to the Nexus 7, what surprised me about the Kogan Agora 10" Dual-Core is that it is quite heavy. Furthermore, even though the Kogan website says the tablet uses USB, the Kogan Agora does not seem to charge with a standard micro-USB charger but has a completely different charging connector, so if you run out of batteries at a friend's house, chances are you will not be able to use his or her charger. I would prefer it if the tablet used micro-USB, but given it's only $180, I'm willing to forgive.

The Kogan Agora 10" Dual-Core has a premium feel to it, even though it is plastic. Although it is heavy, it is thin, black, and sleek. Carrying it around gives off a premium look, that is, until people notice the "Kogan" logo on the back.

If you go to Kogan's Facebook page, you will notice that Ruslan Kogan receives many complaints. Reading his Facebook page, you'd think the man is completely incompetent. But my experience with him (as well as my family's experiences) has mostly been positive. I have purchased a Nexus 7 from him and a car charger. The items took a bit of time to come (maybe a month) but this was fully disclosed on the website and I was happy that it eventually came. Furthermore, Kogan seems to be able to sell goods that are much cheaper than the brick-and-mortar retailers. For example, the Google Asus Nexus 7 sold on his website is cheaper than the same tablet sold directly from Google Play. Kogan also sells a Kogan branded 5" dual-core phablet smartphone for only $150, which is absolutely incredible given most good smartphones from Samsung or Apple cost $600. Kogan may be a controversial figure who has upset many, but there is no question that he delivers for the customer.

Update 9/2/13: I have performed the Antutu benchmark test on the Kogan Dual Core tablet. It received a score of 11505. This is very good.

Google Releases the Nexus 4

A few days ago, Google released the Nexus 4 smartphone and the Nexus 10 tablet. These can simply be purchased online via Google (just click on "Play").

The Google Nexus 4 is now made by LG and has a quad-core processor, a 4.7 inch screen, 2 GB of RAM, 2100 mAh of battery capacity, and a 320 ppi screen. If these numbers mean nothing to you, the bottom line is that this phone is brilliant. It is fast, powerful, and the display is excellent. Compared to, say, the Apple iPhone 5 made by Hon Hai Precision Industries, the Nexus 4 is about two times better according to most performance metrics. For example, the iPhone 5 has a dual core-process, only 1 GB of RAM, a 4 inch screen, and 1440 mAh battery capacity. The iPhone 5 still continues to have excellent screen resolution at 326 ppi.

However, Apple's iPhone 5 cost around $800 to buy outright. The Nexus 4 only costs $350.

Why in the world would Apple create a clearly inferior phone and charge high amounts for it?

Apple's business model is completely different to Google's. Google wants as many people using its Android phone operating system as possible so that users will continue to use Google. This allows Google to make money from advertising. Apple's business model, however, is a traditional business model that focuses on keeping costs low by making sure hardware is cheap (hence the weaker hardware) but making sure demand is high through excellent marketing and reliance on brand loyalty.

Apple's brand loyalty is such that it can get away with taking a mediocre product, slapping an aluminium case with a shiny Apple logo on the back, and double the price.

There are only two main problems I can think of with the Nexus 4: the first is the phone only has normal 3G data transfer speed whereas phones like the Samsung Galaxy S3, Galaxy Note 2, and iPhone 5 have 4G LTE; and the second problem is that, unlike the Samsung Galaxy Note 2, the phone does not an in-built stylus. The number one phone at the moment, therefore, is the Samsung Galaxy Note 2.

iPhone 5 Specs Not Released Yet

The iPhone 5 has been announced. It will have a 4 inch display and be lighter. Although Apple claims it has a A6 chip, there has been no announcement about the specs, such as how many CPU cores the phone will have. We therefore cannot speculate on how the phone compares to other phones, mainly high-end Android phones, the number one phone for now clearly being the Samsung Galaxy Note 2, which has a quad-core CPU with an incredible 2GB of RAM and over 3000mAh battery capacity. It also comes with an in-built stylus and a screen size greater than 5 inches. We will need to see the iPhones specs (including the price) and compare it.

The old iPhone 4S is a big disappointment. Long before the iPhone 5 came out, it sold for about $700 outright, which is about the price of high-end Android phones, yet the iPhone 4S only had a dual-core 1Ghz CPU with a mere 0.5GB RAM. The screen size on a 4S is only 3.5 inches. Screen size is very subjective, but in my opinion the main reason for getting a smartphone is to get internet access and, mainly, to read (and watch videos) online. You just cannot do that on a small screen without squinting hard and potentially destroying your eyes. If you just use for phone for making phone calls and texting, it's okay to have a small screen, but if you only make calls and text, why not spend $50 on a small dumbphone instead of spending $700 on a smartphone? It just doesn't make sense.

The weakness and cheapness of the iPhone 4S's hardware clearly explains why Apple makes massive 73 per cent gross margins on each iPhone it sells and why, even though Samsung is the number one phone company is terms of sales, Apple is the number one phone company in terms of profits. Apple is able to price their phones at the same price as high-end Android phones, yet their phones are weaker and cheaper to produce. Apple today is the world's biggest public company. Customers get less for what they pay.

Hopefully the iPhone 5 is better value for money.

My love of chess

I have been a chess player ever since I was a little boy. I learned to play chess against an old computer program and when I started to join chess clubs in primary school and high school I quickly found that I was okay at it. I became obsessed with chess and eventually became the chess captain at my high school. When I left high school and went to university, I also continued to play chess at the university's chess club, but found that my passion for the game waned considerably, probably because the players at the Melbourne University Chess Club were really good, and I was tired of constantly being beaten. After university I started work and continued to shun the chess world, only playing every now and then. After I received my first smartphone, the HTC Desire HD, I installed chess apps on my phone and found my passion in chess reignited!

For those interested, my favourite chess apps on Android phones are Chess Free and Chesspresso Free. Chesspresso allows you to play chess against people from all around the world, giving each player normally two days for each move. Chess Free, on the other hand, is what I use when I want to play a quick game of chess against the computer.
