I was wondering how long the 11 and 13 inch MBAs would last on Battery while playing games such as Minecraft where there is 3D rendering and internet data upload and download on servers. Also, how long would it last on something like Onlive or a game which is running off the system like Dirt 2.
Just wondering as I don't have 5-7 hours to spend down at the Apple Store and they don't let you download software anyways...
I am thinking of buying one of these so was just wondering as Battery Life is one of the biggest deciders but 3-4 hours non-stop would be amazing.

Also, I know its not supposed to be here, but what about the rMBP?

Regular usage on max brightness (youtube, mail, news, twitter) on the 13" lasts around 5-5.5 hours.

For anything cpu/gpu intensive on the 11" I would imagine roughly 2-2.5hrs. General web surfing, iTunes music, email, depending on brightness roughly 4-4.5hrs. Display brightness kills battery life. 5+hrs if you're offline doing office work (word/excel) and music.

That's why I say my iPad is a great companion to my air if and when the battery does kick out on me while on the road. I have combined 14+ hours of online time.
