My experiences with VMWare, which was a fair bit of time ago, was that it was nowhere near as easy to set up as VirtualPC. I believe the newer VMWare Player is probably much easier to set up though.

I've successfully managed to set up Ubuntu and OpenSUSE amongst other distros in VirtualPC, thanks to google. However, some of these VirtualPC installations have just died suddenly without proper cause :B

And I much prefer Windows 7.
