I went with the Daddy of Mac's and picked up a Macpro in Oct 2006! It's a brilliant machine and does everything i could wish for! I've recently got into editing movies so i'm going to upgrade to 4gb ram and i've just added a 3rd hard drive (320gb)
I've also got a Powerbook G4 17", that'll need upgrading at some point soon but for now it does the job.
Can't wait until 10.5 and iLife comes out! I always thought it was sad "Mac People" trying to tell me how bad Windows was, but now i can fully understand where they were coming from. OSX is just brilliant!
