to cut a read short,
Although you can, you break the EULA by installing Vista Home editions as virtual machines.
You cant compare vista, against any other product, publically, without following M$'s strict (and probably ever changing) guidelines. So no comments like "It runs slower than XP". Thats a no no!
If you do install the business or ultimate editions in a virtual machines, YOU MAY NOT use any DRM secured media or files.
and finallly...
Should you buy a new pc after installing Vista already on one machine, you may not install the same disk on any further machines, even if you destroy any previous installations...
