I've switched from a rMBP to an Air as I really don't need all the performance of the rMBP. The only reason I'd go back to it is because the screen isn't great on the Air after using the Retina display. The Air's display is very washed out looking, the contrast seems to be the main problem. It's a Samsung LCD. I've tried calibrating it but I can't seem to get it right. I really want to like the Air's screen because I like the compactness of it, but maybe I'm too used to the Retina now. Any suggestions?
