I've been happily using both my Air and rMini this weekend and enjoying both tremendously. I've noticed that text appears a tad bit sharper on the rMini vs the Air. I know both of these screens being 'retina' implies the pixel density difference cannot be distinguishable by the human eye, but now that I'm using both extensively I can honestly say that I can tell the difference. The text on the rMini appears as close to print as I've ever seen. The Air is sharp as well, but doesn't appear as sharp as the rMini... The difference is noticeable on websites like Wikipedia where there is black text on a white background. I know I'm splitting hairs here but just wanted to see if anyone noticed this difference as well?
