I kept going back and forth before because of the 15" footprint, but the 13" MBA is just not sexy enough now that there is a retina macbook. now that I'm back home with the RMBP, I'm 100% sure this is the right machine. The screen is ****ing amazing. it's awesome and makes my eyes smile. And if they come out with a 13" retina macbook, I'll just sell this one. I'm sure its value would hold better than the 13" MBA.
