Mac user Alex just sent me two links to video processing face-offs between a dual-1.25Ghz Mac and a Dell P4 3.06Ghz. Who won? The PC, of course, by a huge margin. It's cheaper, too.
I saw a similar test done with Photoshop some time ago (same machine specs), but I can't seem to find it anymore.
Yeah, I know. The Mac is "easier" to use, and it is really pretty, and we don't use it because it's fast. That much is clear. :)
