One thing he missed was that the higher resolution of the Droid allows you to see the entire web page in landscape. This is a big advantage that he did not show. On the other hand, the web and home page scrolling in the Droid seemed jerky in the video, so I am surprised that he said it was just as smooth. The iphone browser was also much faster on wifi as you could start reading the page far before the Droid, even if the Droid finished completely loading the page first.
The larger Droid screen, suprisingly, actually looks smaller because it is narrower. I prefer the shape of the iphone screen.
I am on Verizon so I don't relaly have a choice and I would never switch to AT&T. If the Droid had the HTC Sense or Sony Raphael UI (which look great and have pinch zoom), a better keyboard, and was lag free, it would be all i could ever want in an android phone right now. Hopefully, someone will figure out how to put the Sony Raphael UI or Sense 2.0 on it or at least get the Euro Droid browser working on the US version as it has pinch zoom.
