Hello, I have a 15" 1ghz powerbook now. i am contemplating selling this and then buying a G4 desktop system. Here.s the thing - i do video editing [film major] and the powerbook has always been fine for this. So going to a single G4 tower [can.t afford the G5] would that be pretty comparable? is it worth it? Should i? i.m just weighing pros and cons and am looking for imput. Thanks, Christien.
