Have you looked at Dell's XPS 13 Developer edition? It seems like you are totally ruling out linux even if it comes supported by the hardware manufacturer. I can't imagine Dell released this thing with poor driver support.
Basically the same price as the Air, maxes out at 8GB. I keep hoping someone will just destroy Apple's offering, especially for a product as stale as the Air. One day.
One worry: Linux still has some issues with retina screens, doesn't it? (though distros have gotten a lot better than two years ago when retina was broken everywhere)

I guess you didn't live through Dell (and everyone's) Netbook offerings.
