I don't know how people can look at TN displays. I bought 2012 i7/8/256 MBA and exchanged it to rMBP 15" with additional cost from my hand, but the differences are huge. You get twice for not that much more money, so except for weak people that can't handle 1.5 more lbs a day while "traveling", I can't find any good reason to go with MBA these days. Eventually it's only $370 difference in pricing (if you get the i7/8/256GB MBA), but with rMBP you get: 1. Retina display 2. Quad-core processor 3. 15" 4. Better speakers 5. More ports Cons: Weight, which is not noticeable as a student that puts his computer in his backpack with 1000+ pages books. If you are in the $1000 range area, so yes, MBA is probably the way to go - but everybody else, really can't see a reason.
