Hi, I was wondering if anyone can give me advice on upgrading my old Powerbook G4. I don't have a lot of money to purchase a new MacBook Pro yet so I wanted to max out the current model I have now. The Specs: 15" Aluminum 1.25 GHz G4 768 MB RAM 150 GB HDD The things I want to upgrade is RAM and the HDD. Is it possible to go further than 2GB for RAM and 250GB for HDD? I want to be able to run Leopard on it and even the latest edition of Adobe CS. Hopefully Adobe CS4 when it comes out. Any advice would be much appreciate. Thanks!
