I'll second the outdoor visibility part. I took mine out into the SoCal sun today at noon, and the screen was the best I've ever seen in that much light. And, as I think I stated earlier in this thread: the screen just doesn't look bad to me. I don't see the screen door effect, and the scrolling doesn't bug me if I'm actually noticing anything at all.
I do think it's interesting how some people project their own opinions on others so strongly, to the point where they actually won't accept that something that bugs them doesn't bug some other people. And I need to add again: we're hearing mainly from the people who don't like the screen. Most people who are fine with it won't take the time to comment on it at all.
I think if anyone is considering the Photon, don't go by what people are saying here. Go try it yourself. If I'd listened to everyone about how "bad" it's supposed to be, I'd never have considered it, and I happen to think it's pretty darn good and the phone itself is mostly outstanding so far. I'm certainly enjoying it more than the Epic, and its polish makes me VERY reluctant to ever consider another Samsung product again.
