Here's another review of the PowerBook G4 laptop from Apple, this time by LaptopMag. Here's a small quote from their test report:

The two largest enhancements being touted by Apple are improved battery life and screen resolution. The notebook’s souped-up battery promises to give you up to 5.5 hours of use. When we tested the notebook’s life by running a DVD, the PowerBook stayed alive for just under three hours, which should give you more than enough time to watch almost any movie not directed by Peter Jackson. It also suggests you can get at least an hour more of endurance if all you’re doing is basic productivity chores.
