I have a question regarding the upgrade process on the Al 15" Powerbooks. Do they use removable socket CPU and CPU units? I am wondering because a friend of mine told me the CPU and such could be upgraded over time if you wanted to. Is that true or false? I know they used to offer upgrading on the earlier Powerbooks but i'm not sure about the new ones. I'm THINKING they are removeable socket type units because I doubt Apple would put permanent units in place if they were to offer upgrade=ablity. It would be too much of a hassle. I'm awaiting my new PB and instead of taking her appart..figured i'd ask here. Maybe some one will know for sure. Anyway thanks in advance.
