LT using an Air surprises me because of the lack of screen real estate. I dislike coding at 1280x800 (but I'm usually using Eclipse these days). Heavily customizing Compiz has made 1680x1050 bearable with Eclipse, but I prefer the 1920x1200 dual monitor setup.
LT would probably say something akin to, "real men don't use IDEs."
I'll go for super portable when they put 1920x1200 into a 12" inch screen. (I won't have issues with reading at that density.)
