Don't get me wrong - I like everything about the Mac Pro but you pay for your thrills. I can't afford to lay out that kind of scratch unnecessarily. Apple has done a nice job with the design, no doubt. Meanwhile, I have a high end Windows PC for much less money. The speed thrills me, so I don't need a Mac to get a thrill.
I'm could be jaded from working on Windows apps too long. (I worked on Windows stuff from the 3.1 era through to Windows 2000.)
