I have never owned any Apple product except iPods. I am a PC user since MS-DOS days and now Windows XP. I was at the Apple store last weekend and had a chance to play around with the Mac Pro with 30" monitor. I was very impressed with the machine. I was able to play 5 HD videos at the same time without a hiccup and also able to browse on xoutpost.com at the same time!!

Love the design of the Mac Pro hardware with the ease of adding hard drives/memory, etc. I am already familiar with the current Mac OS.
Wife even approved....Anyhow, went home on Apple.com and configured what I thought I needed on the Mac Pro and configured one to about $6800! I'll have to configure an equivalent Dell computer to see if the Apple is cheaper....
I do know that Apple has an updated OS coming out and of course, one of these days Windows Vista will come out....
