Poll: What do you think is the iPhone 3G's best new feature?

I like my iTouch, no contract, way more room, wi fi to text.Music, movies, video, and no BS. I got the upgrade. Love the remote app. and a few others. No iphone os AT&T signal problems. I'll stick with the Itouch. My car has a gps. If ever you need your phone for directions, you have bigger problems than being lost. Thank You
