I am eligible for upgrade so I will actually make money reselling 5. And even incremental spec bumps will be very welcome, not mentioning end of password enteringI see NO reason for anyone who already has an iPhone 5 to buy a 5S/5C whatever, the 5 is plenty fast enough with a great camera, and if it's the same size screen, you're not really getting anything new.
Apple is lucky that I can wait another year on my 5, otherwise I'd switch to Android because WE WANT LARGE SCREENS.
