I've had my aluminum powerbook for about a year now, and with all the hype of iLife 05, I NEED to play with iDVD. My question is.... what is the best place to go to get a superdrive for my powerbook? Would I be cheaper off buying an external usb or firewire burner? I'm no stranger to installing components on a pc... i've built quite a few. However I have never been inside of a laptop. Much less an apple laptop. What is the ease of installing this drive?
