Congratz on your new laptop! My 2012 rMBP 15 got me started on Retina MacBooks and like others above, I couldn't go back to regular MBA screen. I really wanted to like the MBA 11, but couldn't stand the screen. Now that the rMB is out it's tempting, but I'll wait for the Rev 2.0 with 2 USB-C ports before I consider jumping.
