Well, Macs are STILL easier to troubleshoot when they go down, with better, less
cryptic prompts, thus saving time and energy - but try saying that to a PC
supporter. And Macs are STILL the choice of graphic designers - this is an
argument for which you should be able to find supporting stats. But my district
made a decision to go with PCs, even though we have a substantial base of Macs.
And, after having to deal with Apple over a small school purchase myself, I now
understand a Tech Director's inclination to go with PCs. PC companies NEGOTIATE
and compete in a bid market. Apple is just Apple.
I therefore agree with Sidnie Miller's response of "get anything you can."
Many software titles are cross-platformed, so you can do essentially the same
things. Unless you intend to teach a very high end, job placement-oriented
computer graphics course, the basics are the same on PCs and Macs.
