even the ipad uses sub-pixel rendering for its fonts No, it doesn't. No iOS devices use sub-pixel rendering, ever. Unless you mistake it for normal anti-aliasing, which is done on pixel level. I have less than perfect eyesight. I hold my iPad about 16" away normally. No, I cannot distinguish pixels on the Retina iPad at all. Practically I don't care what is true "retina". For the majority of people, Apple's definition of "retina" is good enough.
