Today, I installed Android 3.1. I don't find there are any big changes yet. It looks very very similar with my new Tablet, Iconia, which is running Android 3.0. According to Google, it will support more USB devices, such as Game Controller. So far, I tested it in VM. That is the reason, I cannot experience their new features yet. Moreover, there is some major API enhancements, such as new USB host API, the MTP API which is allow the developer to access an external camera and new Real-time Transport Protocol API for streaming. I have not started any development in Android 3.X, so I cannot use them yet. Lastly, another good feature cannot tested the new Hardware-accelerated 2D graphics in my box . Even the VM supports it, but I have not a graphics accelerate card at all. Generally, I can find some UI improvements, but I cannout find much other stuff. I need to have a real Android 3.1 device, not just a VM to test!

I want to buy an Android Tablet for ages. But Android is not design for Tablet. If it installs on a tablet, the interface is a kind of strange. Moreover, most of android tablet do not support Android Market, they have to use their "Market" to download the software. Those "Market" have less number of software than Android Market. That is not very good. Besides, most of Android Tablet are 7" screen, that is too small for me. That is not good for using a A4-size pdf.

However, recently, Acer launched their tablet, Iconia A500. That is using Android 3.0, which is the first Android OS for Tablet. The interface is nice. Moreover, it supports Android Market. In addition, the hardware specification is good! It has NVIDIA Tegra 250 dual-core CPU 1Ghz with by 1GB RAM. It sounds great! The price is ok too! If you buy it in Myer, you will get doubled points award. The price of Iconia is $579, which is 2316 points. Therefore, you can get $20 Myer Gift card right now!
Thus, I bought one today. Now, it is charging..... I am looking forward to test!

I went to Harvey Norman today. I found the price of Viewsonic 10s tablet, now is $499. That price is attractive. It got a 10 inch screen. But I think that does not support Android Market, because in their website, they instructed the users to download apps via "AppDowload". Thus, I have to play the real product for a few minutes before I buy it.

Yesterday, I found there is a new option in my status in Facebook, "Question". That is actually a function to setup a poll in facebook. That sounds fun. But I am wondering many people will think this feature is useful. Because Facebook is to connect people, not to collect others people ideas.

According to CNET report, Android 3.0 won't be open source. Google said Android 3.0 is not ready to customize yet. I am not agree with Google. Maybe, changing Android 3.0 will be a bad idea. It won't work as well as its design. But philosophy of opensource is diversity. Opensource community will develop a number of ways to use Android 3.0. They can be good or bad. Definitely, they will be never to be think of inside Google.
