I have noted a number of prominent technologists do their work on MacBook Air 11s or 13s, even Linus. The MBA is in some ways the antithesis of this list, it makes a number of 'nice to have' tradeoffs for a few important things: weight, awesome disk performance and great keyboard and screen quality are these things. I would love to have an LTE option on my MBA, and I VERY occasionally wish I had an ethernet jack on it. I would like it to have a retina display. And I would like it to have 6x the battery life. But, I most often don't worry about my Air at all, it's there, it works, it boots super fast, and if I remember to run make -j4, it compiles relatively quickly. I'm not willing to add 2 pounds to get any of my nice to haves; the combination, while necessarily limited, is as good as it gets right now. For this reason, I think that the MBP 15 Retina is a sort of proof of concept device, the real awesomeness will come when those displays work their way down to the Air line.
