ended up with a white and love it
I was on the lookout for an ATT black one, after a few (4) unsuccessful attempts to snatch one by calling the Apple store to hear "yes we have several and to arrive to hear just sold out" - ended up buying a white one, with the GREEN cover, today.
My original thought was that the black bezel is better for photos, makes the screen look bigger, but now I discovered that the white one looks very clean and "light" design-wise, and actually white bezel is very easy on the eyes, does not distract from web or photos at all. Recall those white margins around photos?
Also, I found that the white one integrates a lot better with my office and kitchen surfaces, that are all white. It just settles in a lot easier into the surroundings being white. So, my guess is that its a keeper!
