Buy a used one and learn about it on the job
My design dept wants to get a couple of G5 Macs. I am in the process of buying some used equipment to play around with and hook into my network. The windows pc just doesn't quite work for a graphics based design program. I never worked on a mac until I got one to test out for a couple of days. Its kind of like coming from the age of the 455 to the C6 Corvette. When change came in he Marine Corps it was Improvise, Adapt and Overcome. Macs are not that bad to work on.
