I think the reality right now is that, for the most part, they don't. IT centers that have to support hundreds or thousands of users aren't going to buy macs, because they'd run themselves ragged supporting them.

That's not meant to imply that macs fail more often, but if you have 500 computers under constant use, you'll get some form of technical problem pretty much all the time.

Configuration issues are solvable by getting the IT staff to learn how to work with Linux, but hardware problems would become untenable very quickly because IT can't keep taking machines to a mac store to get new parts for it.

Imagine the same situation with 5000 macs... you'd have to have an IT staff of 500 people just to keep up with hardware failures that you can't escape from simply because we live in the real world, and physical things break, especially when they're under constant use.
