With the WebOS UI designer and most features you want in the OS, this will be an important step for Android. The OS is stable and mature with 2.2. Actually i like the UI on the Nexus One very much, but i'm sure it can be improved from good to awesome with the team focused on it. Somewhere on Google I/O was a screenshot with Gingerbread on it, but i guess this will change.
