OK, I've been doing some investigating on this, and I've come to the conclusion that I want a new "SuperDrive" for my G4, but I don't want to upgrade my machine just yet. (I'm running a dual 500Mhz G4 that is just fine for me speed wise.) So after poking around, I saw that the Pioneer 104 internal CD-R/CD-RW/DVD-R/DVD-RW drive (a.k.a. "SuperDrive") is the exact same OEM drive that Apple uses, and is for sale separately. It will work with iDVD, Toast, DVD Studio Pro, etc. It's the same drive. Typing in "Pioneer 104" into www.pricewatch.com shows quite a few drive dealers in California that have this drive for around $250 shipped. Here's one info page with a price of $244. This price almost seems too good to be true. The specs on this SuperDrive are the exact same in speed and everything as the current shipping SuperDrives. Anyone have any info or feedback on this, because I'm about to take the plunge.... P.S. For you Apple haters, this works on PCs too.
