I have a question I have a 15" Powerbook G4 back in around 2003 or so 1.67 GHz I just wonder what battery life should I be seeing on a full charged battery? Right now I'm only seeing about 1 hr 30 min or so. Soon I'm going to upgrade to a macbook pro but not any time soon so I figure I might as well upgrade the stock 80Gb hard drive to the largest I can find and the stock memory of 512 to 2GB. Now regarding the hard drive how do I go about cloning the drive? Do I need to move everything over to a external drive?
