I'm a happy user of iPhone 5. As an iOS Developer I can't see much of a difference between my current phone and iPhone 6/6+. Let's have a look at the new things that it has:

- larger screen - 4" is just enough for me;

- better camera - nice to have but not a must, moreover, it seems slightly protruding;

- barometer - don't need it really;

Price in Europe - 900 euros for 64 GB version without contract.

If I can get iOS8 on my old iPhone 5 then I'll stay with it.
