Hello all! Can anyone verify whether or not the final 1.67GHz 17" Powerbook with the high res screen had a different model battery than the previous models? I know longer battery life was one of the things Apple touted when introduced, but I am struggling to find out whether or not the actual battery was slightly different. I need a new one for my PB, but I would hate to purchase the wrong thing. Any of you guys out there with the same Mac have some advice?
