VMWare realized a Player version of there virtualization software: VMWare Player. Basically it is
a version of VMWare that let you do almost everything except creating new
Virtual Machine. The good point is that it comes for free. And even better you
can download optimized, preconfigured virtual machines coming with applications
from IBM Software, Oracle, BEA, MySQL, Red Hat, Novell, and others, from the VMware VMTN Virtual Machine Center. You
might download the player on
this page.

I am curious to see Microsoft reaction with Virtual
PC.
