in fact I've got two. One really old ibook, which is still perfectly fine but as animation compositing and maya are concerned it is, -well not quite up for it. And my new baby is a macPro hmmmmmmmm dribble... soo faaast, -more dribble...

I've used pc's 21 years of my life and I don't think I'm going back unless they change drasticly or run osx.
BUT -thats just my opinion if someone prefers pcs, -fine. I'm not interested in converting anyone here.
