This has been explained several times in several threads. Prior to the new MBA, Apple was not listing a very rigorous battery test time result. They have a more real world case involving the internet and wi-fi being used now. The old 13" 10 hr time was (I believe) either straight idle or just simple word processing. The only people who think it lost time are the ones who don't pay attention. The new processor is 10w higher TDP and the new vcard in the 15 and 17 is 2w higher, so considering they added 35% to their previous TDP and are still pulling 7 hrs on net+wi-fi, I think that's pretty darn good. An improvement even possibly.
