Dream on. Whoever says they get 7 hours are liars unless they get a extended battery or multiple batteries. there are some with 4-5 hours, but no more. A lot of centrinos would give you that. I would go for the 1.6GHz.
My husband just purchased a Sony Vaio fs660 and reviews have said the battery life is awful. Is there a notebook out there with a true battery life of 4-5 hours? I need this laptop to store lots of photos and video.
