What is a Retina display?

Retina is Apple's trademark for a display so sharp that the human eye is unable to distinguish between pixels at a typical viewing distance. As Steve Jobs said: "It turns out there’s a magic number right around 300 pixels per inch, that when you hold something around to 10 to 12 inches away from your eyes, is the limit of the human retina to differentiate the pixels." Given a large enough viewing distance, all displays eventually become "retina."
