Anandtech comprehensively benched the 2010 MBAs as having a longer lasting battery than the 2011 models, my main reason for not upgrading my 2010 models then, anyone have any info on the 2012 models' battery? I hope Anandtech bench these soon, this will be a major factor in my decision to go for the 2012 model, even if it means getting the lower clocked processor to conserve even more power. Also, any word on this configurable TDP? ---------- Just to add that I'm specifically looking at the 11" models, which seem to drain the thing in no time. ---------- Also, I'm very curious to know about the effect on battery not only if you go with the higher clocked CPU, but if you go for 8GB RAM and 512GB SSD vs smaller configurations. Any info appreciated.
