re: Quartz Extreme - I think when you're talking about sexy screen fonts you're thinking of the normal Quartz rendering engine. Quartz Extreme (god I hate "extreme" tacked on to random shit to make it sound more interesting) actually pumps the entire graphical display through your video card's 3D pipeline, accellerating everything with OpenGL.

So all that whiz-bang crap you turned off because it was slow, will supposedly now be insanely fast. The only problem is, the video card needs to have a minimum amount of video RAM of... I believe 32 megs. If you're running a dual 1Ghz G4, I'm sure it's got everything you need, however, perhaps the Jaguar seed you're running either dosen't have QE, dosen't have it turned on, or has an older version. Or all of the above.

What Harry was probably referring to was the fact that his machine has a hardwired video controller that he can't change. Most likely an older iMac or perhaps an iBook. Even the newer model iBooks can't handle QE, which I would think is putting some people off on purchasing an iBook until they upgrade their specs. I know it's certainly stopping me.
