"I'd argue that the reason the iPhone succeeded as wildly as it did is because the one-handed-thumb-operation use case pales in comparison to everything else a big (for its time) touchscreen lets you do." I agree with this statement. A larger display delivers a much better experience when reading text, watching videos, playing games or touching controls in apps. I agree that the "I can reach the corner with my thumb" feature is an advantage. But that advantage pales compared to the fact that a large display (4.3+) significantly improves almost every action that people use on smartphones today. IMHO the only reason Apple sticks with the sizes they use is because they built an operating system that is not designed for multiple screen sizes. [edit: strange comment fail: I actually wote that I disagree with a statement that I actually agree with ;). fixed this now I guess]
