> This statement is true for the range of devices' screen size it's used in, but as the screens are getting better and better, our eyes are now trained enough to perceive the pixels - especially for rounded UI elements.

I'm not quite sure where this thinking has come in. The "Retina" moniker applies to displays based on the resolution, the size of the display and typical viewing distances for devices of that size and type. What science has suggested that our visual systems get better at resolving detail as display densities increase?

Think of when you used a retina display for a while and then looked at a non-retina one:

"ew, why is this disgusting now?"

I think that's what he's trying to say: not that our vision physically improved, but that we started to notice the roughness of lower-res displays.

Imagine a future where all displays are "Retina" at 1-inch distance; you'll be annoyed that when looking at a lower-res display it won't show someone's nose hair.
