I was amused at Apple's "Word to the wise":
Windows running on a Mac is like Windows running on a PC. That means it’ll be subject to the same attacks that plague the Windows world. So be sure to keep it updated with the latest Microsoft Windows security fixes.
(Yes, the link was there in the original.)
Personally, I can't see anyone buying a Mac just to run Windows on it. To me, the big advantage of the Mac is OS X. It blows Windows into the weeds. For folks who have software that they have to run under Windows, though, it's a viable solution. It looks like it's got the standard Apple ease of use, including a clear graphical disk repartition utility, and automatic generation and burning of a CD with drivers for the Apple hardware. Since my company is about to start using a package that's only available for Windows to run its entire business on, I'll probably wind up having to use it.
