So I picked up my 5s today in space grey some observations: I previously had 64gb 5 in black this phone looks way better!!! The fingerprint reader is amazingly fast and has been flawless!!! I am blown away and would never go back to entering a passcode number. The photos are drastically improved. The speed difference is very noticeable web pages load almost instantaneously on my wireless network. I had been running a developer preview and the final version of iOS 7 for weeks and it is way faster to my perceptions on the 5s If your on the fence don't look back, for me the improvement in the camera alone would be worth it! The purchase process at the chicago store was smooth as could be, They gave me over $200 + credit(don't remember the exact amount) for my beat up iPhone5 At 7:00 pm there was still a long line. The sales person stated they still had stock in several 5s configurations, out of white and gold! People in the store were buying the 5c as well. One last thing I forgot to mention. When I went from the 4s to the 5, my feelings were great phone was impressed with how thin it was and nice screen. So far the upgrade to the 5s seems much more substantial as I said above the camera improvement and fingerprint sensor are a really big deal once you start to use them to me more of a wow factor than the 5 was with its amazing thinness and bigger screen.
