Hallo, I already own 2 notebook (Toshiba P4, and FSC P-M) both give me a bit more than 2 hs (with linux, no idea with winblows). I'm in the process of getting my first Mac, a MacBook. After I decided that I'll get one despite HPs and other costing a bit less (but having to endure removing winblows and installing linux, of course), may last question is how much battery life can I expect ? for example, in light use conditions (text-file edition), DVD playback, etc ? A straight answer would be most helpful thanks.
