My vision isn't great, so I upgraded from my iPhone 4 to the 5 because of the larger screen, and the 5 to the 6+ due to a larger screen.
Really, the screen size has been the main driving factor in my phone purchase decisions.
My 4 & 5 have been passed down to my mother, so they're still in use. Hell, I was still using my 1st gen iPad until just over a year ago when the screen just failed.
