I just got my Galaxy S upgraded about a month ago. Today, I found there is Android 2.3.5 update. The speed of rolling out is getting faster. I believe Samsung is working closer with Google.
Moreover, I found the new version have some performance enhancements too! I am already happy enough about it.

I have upgraded my Iconia A500 to Android 3.2, I have plugged it with USB Network Card again. That is still not working!!! I think even the OS is upgraded, it won't work! I believe USB Network Card cannot use with an Android Tablet, that is not a recommended way from Google.

That's quick, my Acer Iconia A500 has another update! Yesterday, I downloaded the latest update from Acer. Today, I got it updated to Android 3.2.

The first enhancement I picked up is the performance. It seems to get 2X speed! Maybe, I will find more new features in next few days.

I got a Galaxy S. I just upgraded to Android 2.3.4. That is the latest version of Android. That is similar with Galaxy SII. I do not play games. Thus, I do not need a fast CPU. Moreover, I am still happy about the screen quality. That is better to keep my old Galaxy S.

Google announced they bought Motorola Mobility. I think that is good for Android. Motorola already has Android phone and tablet. I believe they will built more. Thus, Android will be brighter future.
