I have a launch day iPhone 5 coming out of contract in 10 days. I am now thinking of keeping it for another year until the 6S (or whatever it's called) comes out next year. What is the future outlook for the iPhone 5 into 2015? Given that Apple is still selling the 5C (internally same as the 5); can I expect apps to work reasonably on the iPhone 5 for a year more? I know, I won't get cutting edge performance, but I can settle for an extra millisecond or two here and there. I'm also not planning to upgrade to iOS 8 to preserve performance.
