Hello! I have a 12" Powerbook which I bought last year and I love it. I have one problem though. The battery life is a little bit too short for my practical uses and it is one of the most important aspects of having a portable for me. The iBook I hear has a much longer battery life which definitely appeals to me. I use the PowerBook to make iMovies, surf the net, chat, use Office 2004 and that's pretty much it. The iBook is also inferior to the PowerBook in a number of ways hence the cheaper price. What do you suggest that I do? Should I downgrade to an iBook or keep the PowerBook and sacrifice battery life?
