This is pretty much what I expected. It's not ridiculously faster than the 4S. Now, next to a regular 4, you would notice a huge difference.
Read in a few reviews that the speed increase on the 5 is noticed mainly when loading games/heavy apps. But when just scrolling through the phone or browsing safari, the speed difference between the 4S and 5 wasn't vastly different.
Either way, my 4S is fast, and since the 5 is obviously faster, it's gotta be a little beast!
