Since the announcement I've read lots and lots of commentary, but nothing that suggests that the 5S is a worthy upgrade for someone who currently has a fully functional iPhone 5. At this point the iPhone 5 is just a year old and has the same specs as the newly announced iPhone 5C. It runs iOS7 without issue or any noticeable impact on speed. It runs every application on the app store quickly and without problems and will do until at least the iPhone 6 is released. The camera hasn't degraded overnight and is still better than most smartphones. Apple have literally taken the iPhone 5, and made evolutionary improvements that aside from the fingerprint sensor unlocking the phone aren't things that are going to be that noticeable in standard day to day use. Can we all agree that if you have an iPhone 5 there is no real reason to get the 5S?
