Hi, I'm a college student interested in switching to either an iBook or a Powerbook from my Windows desktop computer. I have read some reviews citing poor battery time on the Powerbook. I've also read that the iBook gets better wireless connection with the Airport card. Basically, I'm split between the two: the performance of the Powerbook and the cost of the iBook. Which would you suggest? I don't expect to be doing anything too intensive: some web design, office applications, music, and watching movies (maybe editing?). Also, Apple only has a 1 year warranty for the laptops. Why so short? I'm kind of nervous if they're only going to stand by their product for a year. Please offer your suggestions.
