The beauty of Macs is the standardization and reliability. It doesn't
matter if machines are replaced with newer machines, one image can
re-image all of them. You aren't hunting for drivers. I've got one Intel
image for OS X 10.5.5 that goes on every single Intel Mac we have, from
the Mac mini, to a couple of different revisions of the iMac.
As for reliability, with only 24 machines you will probably run that lab
for 5-10 years without a failure. (maybe a hard drive, but those aren't
hard to replace if the machine is out of warranty).
As for me, I still have All-in-one G3 macs from 1998 running as
thick-clients to my LTSP server. Macs last forever.

I agree completely with this and think it would be a very good direction
to go. I can understand why the teacher wants to have Macs for a
multimedia course. It's very difficult if not impossible to compete
against Garageband, iMovie, Keynote, and iPhoto with OSS solutions.
Someone else said in this thread, the best tool for the job. That's why
I support OS X, Linux, and Windows.
