Charlie Stross, iPhone-user, makes the case for a 4-inch display.
I disagree with his assumption that one-handed usage is mostly about voice calls. I use my iPhone one-handed, as a communications device, all the time. It is true that typing works far better two-handed, but Siri should alleviate that problem too, particularly for tweet/SMS-length input.
Good argument, though.
