Hello! I have been offered a PowerBook G4 against one of my guitar amplifiers which is roughly worth around 1000$. His powerbook has 2gb of ram, and seemed really quiet when he brought it over. I've always wanted to get a mac, but I'm not sure if I can rely on a powerbook with all these new 'macbooks' out today. I have never used a mac, by the way. Is the Powerbook G4 still a computer I would be able to rely on for a long time? I would use the computer mainly for audio recording/mixing, video editing, and net browsing. Would the computer do well, or should I just buy a new macbook (which has a smaller screen)?
