You know, in my intro I said I was neutral in the great Mac-PC debate...that was actually a lie.

If you're going to do anything
useful that has to interface with another computer...GET A PC. (Unless your theatre runs on Macs, then by all means get a Mac.)
Apple loves to talk about how much they've improved the quality of "compatible" files between Macs and PCs; this is borderline false advertising. If you create a file on a Mac and then run it on a PC...expect to do some MAJOR re-formatting. In my personal experience, bullets almost never survive the transfer, imbedded objects (like tables and some graphics) often refuse to work, and margins/tabs/indentations go nuts. (Of course, if you don't use any of those things, then don't worry about it.)
Macs are very powerful machines. They can do a lot of amazing graphics work, sound and video editing...but you want to know the number one program the Macs froze on in the Mac lab in my university? Would you believe
iTunes? A program that came standard on all of them? Why oh WHY can a Mac run Final Cut Pro like it's nothing...but goes belly up on iTunes?
Honestly, I spent WAY too many nights in the newsroom at the school paper cursing at the Macs for freezing (which they did CONSTANTLY.) I've worked for two different student newspapers; both had written instructions on every Mac monitor to save
every five minutes.
And while this is good advice for anyone running any platform, I have to say that I've never worked with more computers with poorer "document-recover" functions than those Macs. And they were brand-new, top of the line models, too.
Furthermore, I once watched a "practical demonstration" of Virtual PC (the program that allows your Mac to pretend it's a PC) and it slows down the computer SO MUCH. This may or may not bother you, since it's not incredibly noticeable when you run programs like Word, but it's there. Expect everything to run about 25% slower. And Virtual PC isn't cheap, either.
Honestly, Macs do have some advantages over PCs...especially if you do a lot of graphics work like me. There are many times I prefer Macs to PCs...but trying to get my Mac to play nice with my theatre's PCs is NOT my idea of easy or convenient. If you can only choose one for work-- go with what your theatre has, which is probably a PC.
To review: Macs are happy when they don't have to play with other computers and don't have to pretend to be PCs OR do PC-compatible work.
