I lucked out this morning and only had 10 people show up before me in line. As I expected, the finger print sensor is tremendous and for me very helpful. The fact it can and very likely will be expanded in the somewhat near future to make purchases in stores is an added benefit.
LIke some here, I was coming from the 4S, so this phone is crazy fast, especially the internet. The phone I have actually found a little bit worse of cell signal strength which is a bit weird so far. Siri seems to be pretty well improved as well. If you like playing games though, that might be where the 5S stands up most, the graphics and smoothness are excellent, well above the S4 or HTC1.
So far overall and excellent phone.
