I'm going to keep my 4s until it falls apart and then evaluate the market.
I really dislike the current trend for bigger phones and I hope apple doesn't follow the herd on that one (or at least keeps a smaller phone available).
If it does and the only iPhone available is a behemoth I'll probably look at one of the smaller Android phones. If there's a smaller iPhone available, I'll definitely get that
I agree with this. I am not really into these ginormous phones. I really prefer the smaller 4s, and I didn't bite on the iphone 5 because my 4s has been plenty of phone for me. I have tried android devices, and I am just not into the UI. It is a bit all over the place for me. iOS while kind of structured and limiting, is clean and relatively bug free. I'll consider picking up maybe an iPhone 6 or something like that.
