Interesting. Engadget writes:
"In another video playback test -- specifically playing a movie file "in full-screen mode at full brightness, connected to a Wi-Fi network, with the backlit keyboard dimmed, and volume on 2" -- MacWorld tested both the 11-Inch and 13-Inch models and reported:
Roughly three-and-a-half hours for the 11-inch model and five-and-a-half hours for the 13-inch. Those figures were both improvements on the battery life of the previous-model Airs. (The increased speed of the build-to-order Core i7 processor option didn't have a major impact on battery life, either.)"

So nobody is getting close to those numbers?
