I've had mine for a couple of weeks now. The OS doesn't quite have the Apple polish, but it all works and it's nice to be able to run things in the background. I used the navigation for the first time yesterday, and it got me (somewhat ironically) to the dealer to whom I sold my car, thereby working itself out of a job.

As far as I can tell the bottom line is this: Droid has a better network, while iPhone has better apps. Pick which matters more to you, and you know what to get.
