previous generation powerbooks?

Hi, I was wondering if anyone has the specs of the previous generation 15" powerbook? My reason is apple is selling them for $1,600 new not refurbished. My main reason would be because it has an ati graphics card instead of Nvidia. Otherwise I'd end up buying a 12". Oh yea just a random question but does anyone know if slot loading drives can play mini disks?

the lowend 15 was 1ghz and the highend has 1.25 and superdrive with ape, and i think both came with 64mb ati 9600. i dont think the slotloading drive will accept a minidisk, imean it will accept it it will get stuck there i presume.

Never use a mini disk in a slot loading drive! Bad Bad Bad...
