Way back in the day, I bought the top of the line 450mhz G4 (AGP 2X) with the DVD-RAM drive. Is this drive of any value today? Can I use it for anything other than small data backup? I have over 120gb on my system total (2 drives). I think the only discs you can use with this drive are the double-sided Type-2 DVD-RAM discs, which only hold 2.7gb on each side. Is that correct? Is anyone finding a better use for theirs? If so, where are you getting your discs? The reason I ask is because I have been considering replacing it with a Superdrive. Does anyone know of a list posted somewhere of compatible 3rd party superdrives? I know that most of the Pioneers, some Toshibas, and maybe a Sony and Hitachi drive are compatible, but as to what numbers I don't know. Any help would be great!
