Got mine delivered at 10am this morning. First impression is the brilliance of the build and the materials. I'm still not sure on the screen, had a s2 for 3 months as a stop gap between my 4s and 5 and I don't think it is big enough, not such a nice browsing experience and I'm missing some android os features (cant believe I'm saying that)
Camera is superb though, the speed you can snap is insane and quality in low light is better than my lumix compact camera. Panoramic mode is brilliant too. Suppose what's spoiling it at the moment is the lack of iphone 5 modded apps, everything except facebook and twitter is running 3.5".
Gonna give it a few days but I may go back to the s2 and pop the 5 up for sale
