If it didn’t make sense to Google to support Android 2.2 or 2.3 on tablets because it was not optimized for tablet use, why does it make sense to have a UI optimized for a tablet on a smartphone? Earlier this week Google released a preview of Android 3.0, and after looking at the screen shots of the UI designed for a tablet, I got the feeling Google was going to fork Android. Perhaps forked is too strong of a word, what I really mean is that it looks like Android will have two UI shells, one for tablets and another for smartphones.
