I don't understand this question I've seen floating around - "do you need a retina display?" If you are literate and read things on a computer, you need a retina display. I went to the Apple store and spent about 10 minutes on it to really get a sense of what I was looking at. When I moved back to their regular screens, it felt like a world of difference. My eyes felt far less strained with the retina, and I'm considering buying one over a 13" Air just for the screen. Hopefully this is da fucha for all computers - not just Apple's.
