The DVD-RW/CD-RW is available for Apple PowerBook G4s, too! I use a first-generation PowerBook G4 as my primary computer, upgraded to 20GB HD and 1GB RAM, and I'm very happy with it. It handles Poser 4 very nicely, whether in native OS 9 or Classic mode. The only (very slightly) awkward thing about it being a laptop is that there's a bit of a contrast shift from the top to the bottom of the LCD screen if you're not looking at it straight on.
