I've thought about doing a Review/How-To-Use of Hyper-V in Windows 8.  I asked & answered this question:

https://superuser.com/questions/472499/how-do-i-install-and-use-window-virtual-pc-in-windows-8

And found/answered this one as well:

https://superuser.com/questions/469806/windows-8-hyper-v-how-to-give-vm-internet-access

There are a few other features that I can go into detail like:

 - Overview of Snapshots
 - Requirements for being able to run it
 - Talk about the [special case that Windows had to make][1] for Adding Wireless NIC's being accessible to the VM's
