Recently, I went to Hong Kong. I bought an Android Dongle(MK808). That is so powerful. Although that is very small, it is similar with a USB thumb drive, it has Android 4.1.1, Daul Core A9 CPU , 8GB storage. That is so powerful!

It turned my TV into an Android TV. I can browse the websites and watch youtube in my living room with a big screen. Its speed is ok and I can install the apps from Google Play in that. Generally, it is a small Android computer. Moreover, it supports Bluetooth and wifi, with two USB ports and HDMI!So it is so cool and only costs HKD$658.

I found the cloud solution is essential for my business. That is so hard to keep our own infrastructure. The cost is not just for buying some hardware. The difficult part is requiring someone to maintenance them. Moreover, we need some applications to access from multiple locations. Either we have many laptops
or going to cloud ...

I found there are a few type of people willing to buy apps in google play in my circle of friends.
First of all, they are local australian , not Hong Kong people. They are happy to spend some money in good app. Most of Hong Kong people are still thinking android apps have to be free. Well ,there is no free lunch in the world.
Second type is ex iphone user. They get used to buy apps in appstore. Paid app is nothing strange to them.
Third one is business users. If they will buy any app which can increase their productive or earn money, they are very willing to buy those apps.

If you want to build some paid, you can target those kind of people

Recently, Whatsapp need to charge some of their android clients. As an Android developer, that is not a bad things. Most of android client ever bought anythings from Google Play. I believe there will be a number of users need to enter their payment details. After that, if they want to buy other paid app, they just need to click and their password again. That is easier. Moreover, after their first times to buy a paid app, they may think that is not too bad to spend one or two dollars for buying an app. That is good for us.

I upgraded my Galary S3 to Android 4.1.2. After that, I found there is a side bar on the screen, that sounds a Windows Desktop on my phone. That is good to have some short cuts like this. But that is too little. I don't like it much. I don't think that is useful for a Phone UI.
