Rectangular Power
Well, I got my hands on a Powerbook G4. One of the first model ones. I've already managed to drop it, too - nice big dent on the bottom panel. I'll be able to hammer it out eventually.
I've installed Linux on it, and it's fairly lackluster. The 3D card doesn't work properly (seems to be a problem with newer Linux distros - it's a Rage 128, and should be very well supported) and like most Mac laptops I've seen, it can only display at its native resolution. Come on! We neeeeeeds our gamezes!!
Also, the hard drive sounds like a jet taking off. Awesome.
I'd take a picture if my bluetooth module weren't dead :(
