Hi everyone, I'm new to this forum but have been using Mac products for about 7 years now. My powerbook has to have the worst battery life around, even with all the energy saver options used to conserve the life of the batt, and the screen and keyboard illuminated to just visible, the mosy I can get out of it is about 1 hour and 30 minutes. ANy recommendations on where to get a new battery at a decent price?
