The only downside I've experienced is really one that I'll lay solely at the feet of Windows 8: If I go a long time without checking in on the Windows 8 VM, it will sometimes auto-install updates and then force a restart. This has rather horrifying results if I had also neglected to save a file I was working on.

Moving back and forth between working on the same codebase on both the Mac and Windows sides is also a little irritating; I find the best way to do this is pumping the data back and forth between them using Git. But that would be what I have to do if they were separate physical machines, too, so I'm not terribly prepared to whine about it.
