I have a Mac Pro and love it! Mac is so much more intuitive than a windoze machine. I run Parallels so that I can work on several things at once. I run Leopard 10.5.8, Windows XP, Ubuntu Server, and Ubuntu OS virtually. I also have laptops running XP, Vista, and Windows 7 virtually, I have these primarily for remote tech support, certain Windows versions do not like to play nice with each other!
