So... a month of 16 hour days (no days off) later and extremely flush with cash, I'm looking to pick up a 17" Powerbook G4. I've read up on the specs of the different models, but haven't seen much about which models were the best/great/merely good/problematic. What are some of the members' experiences and recommendations here? I'd like to grab one that's the perfect balance of stability and speed, and, of course, max it out.
