The main use case for the bigger screen, that I've seen, is people watching video content. This is a very common use of the smartphone in places like Singapore. I was surprised how many people had smartphones and used them despite only having 3G service -- it's because they preload with video to watch on transit. I assume much of Asia is the same way.
