Despite what you think, I do appreciate you posting this. Somehow I had missed the poll. I was curious where people here at macRumors fell on this issue. Obviously all posters here didn't participate, so it's not a very accurate poll.
I see two other problems with this:
1. Even if 99% of all Macrumors posters wanted a larger screen, this still is a very small subset of overall iPhone users. Apple is not going to make a change like this to make 10% of users happy. I have many friends and relatives with iPhones, and they are all super happy with them. I have never heard any of them lamenting that their iPhone had a small screen or wasn't as good as their friend's android.
2. This poll is assuming that they could cram a 4 inch screen into the same size unit, but I don't really believe this is feasible. I'm sure people have done the math and that it is technically possible, but I don't believe Apple would design this. If the screen is edge-to-edge and almost completely top to bottom, then it would be very difficult to hold and use without triggering unwanted actions.
Of course, this is all speculation. Only Apple knows what is coming. I just wish I wasn't as invested in this as I am so that I could be more patient.
