I'm thinking about getting a powerbook 17in, and I need some advice on how to configure it. now I (eventually)want to max out the ram, so how much do you advise me to get when I order it? (there is one dimm that you can't remove, so I'd need to max out the nonchangeable slot right?) anyways, any other advice would be welcome, I edit film alot and am on the move alot, (and maybe some games may somehow find there way on, [halo, ut2k4]) thanx!
