I have also been a Mac user since the Mac Plus, and a Computer Tech for the last 20 years, on both sides.
I have a MacBook Pro 1.83, My wife has my old Powerbook G4 1.25, my son has my even older Powerbook G4 667, and I also have a 1.33 XServe in the house.

Yes I do have a Windows machine, in my son's room, 3GHz, it's lonely and gets little use.
