A Colleague of mine uses a Powerbook G4 with an 80 Gig. external Maxtor Firewire Drive and FCP. The only thing she said was that she had to periodically format the video drive to maintain accuracy and reliability. Other than that she loves it. You can also use Firewire drives on PC machines and save youself some money, or even check out the new IBook it's got a G4 processer with velocity engine just like the last G4 Powerbook.(posted 8076 days ago)Rob Rock www.bluewater-media.net
