I hate the look of the bigger screen and for me personally a 0.5" taller screen isn't going to help me much. I mean it's a lot tackier than the 4/4s. The more I see it the more it looks like a tv remote to me. Meh, so the camera is slightly better, a little better battery life, and some what faster than the 4s. It still doesn't make my 4s any worse than it was once it came out. Plus my 4s is still gonna get ios 6.
Oh and the lightning connecter is gonna be hell with all of the they previous 30 pin accessories that won't work now.
Now if I had a 4 or even a 3gs and my contract was up I'd probably get the 5 but for now I'll just stick with my 4s.
