I hadn't seen this in any of the blogs I monitor, so I thought I should share. Parallels, Inc. has released their Parallels Workstation product. This is a complete virtualization solution much like Virtual PC, and VMWare (I know there are others).
There are a couple cool things. They boast that they are the first virtualization app that includes Hypervisor technology. This is supposed to make things perform a bit better. From my observation it does appear to work pretty fast (no worse than running another app on my laptop... I am still testing check back here later for more detail).
The other very important thing to mention is price. Parallels Workstation is $49! I believe this is a lot cheaper than Virtual PC or VMWare (although VMware does have the free VMPlayer that can be manipulated --by hand-- to let you create new virtuals).
You can also get a 45-day trial of Parallels Workstation at their web site. I own Virtual PC, and I may actually spring for a license of this depending on the results of my testing (which I'll post here).
