While I realize heat is an issue I would have liked to see the 2.26 w/upgrade to 2.4 on the 13" MBA as the two CPU's. The GPU is honestly better than I expected. I have no issues with the battery as the MBA is about weight/portability first and foremost and for web browsing, email and my work VPN I have seen on at 7am running until 3:30 or 4pm with avg use. Not non stop but in between calls and such I use it all day and while Monday it was at 2% at 4pm it did make it without having to charge. No complaints of 9 hours of standby with constant use. I would guess a easy 6 hours of usage.
LTE, when it is actually rolled out and widespread would make perfect sense for the MBA but at this point I'm sure they left out the 3g chip, the backlight and anything else that would suck down the power to improve battery life.
All in all the new MBA is probably one of, if not the best laptop experience I've used. Portable, powerful enough for my needs and decent battery life. I can't wait to see what's next.
