A starting point:

http://en.wikipedia.org/wiki/Virtualization

To give you an example, for me, virtualization is useful to run Windows
XP from within Linux/Ubuntu, this allows me to run Windows applications
when required, while still staying in my Linux environnement, my
platform of choice. 
I also use virtualization to install and test the
developement version of upcoming Ubuntu releases, without risking my
"real"/host machine data. I can do any number of massively stupid
mistakes in the virtual machine, with the full confidence that
absolutely nothing can happen to my "real" machine/environement, total
peace of mind.... that's priceless.
I also use virtualization to evaluate other Linux
distributions evey now and then.
Virtualization is just sooo useful, it's magic :-)

I agree that virtualization is very useful. I have been running Ubuntu 6.06 under a virtualpc 2007 under WXP. The  one problem I have run into is that 6.06 works great but 7.04, and 7.10 will not install. 7.04 installs but the screen resolution is unusable and I have not been able to convert it to 1024x768. I had the same problem when I installed 6.06  but was successful when I used the safe mode. For 7.10 it installs in safe mode but the mouse won't work. If I install 7.10 in standard mode I get the unusable resolution. I was able to get into the command menus with Alt F1 but I can't change any settings. 

After all this any thoughts? 
Vic
