I wouldn't make a big deal of potensial problems with Haswell, you'll only be using the IGP anyway. Apple seems to do a fine job of messing up the OSX in general these days...
I'm still using my MBA 2010, and will buy the very moment Haswell MBA 13'' is available. That MBA model will have a significant upgrade in graphics power (games, big external monitors), and yet remain very portable. Hopefully (I'm guessing here) the Haswell should also run cooler, because of the focus on longer battery life and lower power usage.
All this rush to constantly upgrade every or the other year is nonsense IMO. My 2010 MBA still runs like a champ, and runs cooler than the newer models.
