The main reason some like larger screen phones from Apple is that they use it as there main computer, not as a phone anymore, and like its portability, not wanting to use a computer at home for games, etc. Kids like to text friends (A lot) that may just be sitting next to one another or nearby. Like to play games, movies, music, etc, thus the main reason they complain so much about the screen size all the time.
Tim Cook mentioned not too long ago that he wanted the iPhone to be easy to use with one hand, which I agree.
Professionals/Business people want to use it for calls, some texting, and emails, but no games. Music, very little. Older adults (above 35) mostly do not want a huge iPhone either. They use it to make voice calls to keep in touch with the kids, some texting as well, or GPS, photos but no to very little games.
Some, however, in the older category also may wish for the larger phones, but they do have them now, if they would just migrate over to Android. Simple but they won't
Apple may release two iphones someday to satisfy the younger generation, but until then, they will always complain about the current size of the iPhone, instead of just heading over to the Android phones that are out already to satisfy their needs.
I like the 4S and the 5, and hope Apple never goes wider unless they release two iPhone, one for the kids and one for those that still talk on the phone.
