Why would anyone with an iPhone 5 upgrade to this ? Can anyone give me a reason ?
There is no reason to leave an iPhone 5 to a 5S. Nothing spectacular other than the A7 processor, the Touch ID and the camera tweak.
Next years iPhone will see drastic changes as usual. This upgrade is only for those that haven't upgraded in awhile, new to the iPhone or is on the "S" cycle when it comes to upgrading every two years.
