I'd get about 9-10 hours on a Macbook Pro simply lazily web browsing. This is theoretically reported battery life, however. I never actually let it run down to 0. It's possible the last 10% would have vanished in 30 minutes instead of ~2 hours like it claimed. I can certainly believe a Linux machine can get 14hrs. It's just a matter of having a bigger battery, and a processor that will step-down its speed when its not needed.
