Android Fork Speculation

As someone who likes Android, I am nervous about how Google seems destined to make the same mistakes as Microsoft. In my opinion, the high number of different Windows Mobile builds (touchscreen, non-touchscreen, Smartphone, Pocket PC, Pocket PC Phone Edition, etc..) made developing and releasing new features too complicated and time consuming. The slow pace of change with Windows Mobile is the main reason why Microsoft has lost so much marketshare in smartphones.
