I use an app called Synergy that lets me use many displays with one keyboard and mouse across many computers.
Here is a pic of my home office

The PPC with MS Direct Push email would let me send corporate emails with out a VPN. It would be great to be able to use the mouse and keyboard to control my PPC to send emails.
