I am also glad to hear about the big changes coming to Android's camera controls, which have long lagged the competition. And who's not excited about HTML5 support?
We know that at least one device this year -- Motorola's Droid -- will be running Android 2.0 out of the box. Hopefully others will hit the market with 2.0 on board, and the existing crop of Android phones will be able to update to the latest version of Google's mobile OS.
