"Steve Jobs said that the human eye, viewing a display from 12 inches away, can’t discern individual pixels if the density is over 300 pixels per inch. Except that this “magic” number is wrong. The real number is closer to nine hundred pixels per inch.
Apple’s definition of Retina is based upon the vision of seniors."
Apple marketing, for the win.
