Anyone make the switch from an 11 inch air to a 13 inch rMBP. If between a 13 inch air and rMBP i would take the rMBP for my needs. But the 11 inch air has a different level or portability. When I look at them in stores it doesn't seem all that different, particularly since I usually carry and iPad and 11 inch air, and am going to shave weight off with a new iPad. But I wonder how one will feel after a few hours or carrying day to day. Or does anyone have side by side pics?
