As far as the API goes, it doesn't bother me how it's implemented when I'm using the phone
Fair enough. This thread can be deleted if no developers read this board.
The news for the end user is that pinch-to-zoom, etc, while not completely new, is becoming more mainstream. It's now in the base apps of Droid and Nexus One (where it wasn't at intro), and will become more common in third party apps as well.
