If the 5 was not compelling enough to get you to upgrade, why would you buy the 5S? Assuming the generally accepted rumours are true, it's just the same phone but faster, possibly with a fingerprint sensor. The 5 is a great device and I'm sure the 5S will be too. I see no reason NOT to upgrade. I just don't understand what the 5S offers that would tip you over the edge when the 5 didn't?
