I guess the practical question for me is: in case Fusion goes abandonware, is there a viable desktop-focused hypervisor for the Mac other than Fusion or Parallels that runs Windows relatively well? I'm on Fusion, and I've always kind of viewed Parallels with suspicion. There's Vimy and LTM but as far as I can tell, they don't do Windows or GUI's all that well, since their focus seems to be linux and Mac OS X VMS, unless newer versions have improved...
