My G3 blue 'n white tower is starting to show it's age and I am looking to get a G4 Powerbook soon. Mostly for music applications.(logic, mp3s, etc) I have messed around with a couple over the last few months in some shops, but could not really get a good feel for them. How has your experience been with it? Good/bad? Would you suggest getting one? Any pros or cons I should know about? I also wanted to know what is the difference between the SuperDrive and the regular drive.? (please excuse my ignorance!) thanks in advance.
