I don't know about you, but to me the difference between a display like that on the iPhone and one like that on the HTC One is night and day. You can pick out a pixel if you look for it on the iPhone, but not on the One. It's even noticeable when you look at them at a normal distance. The One's display looks smoother even if you can't say that you see an individual pixel. You'll discover the difference when the iPhone gets upgraded to a higher resolution.
