I was hoping to upgrade my 2011 MBA 13" to the 2012 MBA 11", but was disappointed that they could not find a way to improve the battery life for the 11". That's the one I always wanted, but picked up the 13" last year because the battery life in the 11 incher was just too little (4-5 hours). I waited all year hoping they could bring it up to par with the other models at 7 hours since I do a lot of work outdoors.. but just didn't happen. It's not the ultimate portable machine to me (although it is a good one), if you have to carry a charger around with you when you go out. I rather carry a 13" MBA with no charger than a 11" with a charger I guess..How many others were disappointed about that?
