I'm curious as to whether the new longer battery life has changed how people use their MBAs? I ask because I normally work in my office where I plug in my laptop, and then go home where I have another charger. So I'm not sure how the longer battery life would make a difference. Even when I travel, it's rare that I take a flight longer than 5 hours. But maybe there are new ways to use the laptop that I'm not considering!
