If your eyes are young and you only use the phone alone. If you are older you need reading glasses for small screens. If you are showing a video to someone else you need a larger screen to see detail. of course not knowing you or your uses I can't say if any of this should matter to you. Still it seems like a nice idia not a fad. Only time will tell if people really want it once the fad is over.
