Yeah, I liked Beevis & Butthead too, then I started Junior High.
I need a Quad G4. I edit a lot of digital video using programs like Final Cut Pro 2.0 which can take advantage of multiple processors. The faster I get a job done, the more money I can make. With a Quad G4, rendering jobs that would take a minute or two on my G3s or a minute on my G4, would take a matter of seconds.
I'm not saying there's a huge market for quads, but I'm saying is there's a good number of digital businesspeople/artists like me who could use the oomph, and more importantly for Apple, would be willing to pay for it.
