Have you ever wondered why during the evolution of iPhones, right from the first model to the recently announced 5th generation iPhone 4S, the screen has retained the same dimension?

Although many of the contemporary phones sport a much larger screen of more than 4″, why has Apple stuck to the 3.5″ screen for iPhone?

Dustin Curtis has probably found the answer – simple human ergonomics:

Touching the upper right corner of the screen on the Galaxy S II using one hand, with its 4.27-inch screen, while you’re walking down the street looking at Google Maps, is extremely difficult and frustrating.

I pulled out my iPhone 4 to do a quick test, and it turns out that when you hold the iPhone in your left hand and articulate your thumb, you can reach almost exactly to the other side of the screen.

This means it’s easy to touch any area of the screen while holding the phone in one hand, with your thumb. It is almost impossible to do this on the Galaxy S II.
