iPhone 6 is a great phone.
iPhone 6 Plus is a BETTER phone.
I get alot of old phones given to me from my relatives. Junkie old phones from 6-7 years ago. I was just given the original BlackBerry Storm today. Looks new for its age. Just like last week when I was playing around with the iPhone 3Gs and iPhone 5 before that, I am now playing around with an older Storm (Verizon) from 2008. This screen is even smaller. Very, very difficult to go back to screens smaller than 4.5" but I remember how phones like this and iPhone from 2G to 5s were ideal for one-handed use. Now I find them difficult to really do anything. With the Apple Watch release next month, I think smaller phones (4" screens or below) probably wouldn't be needed as much either.
