Difference between Microsoft Virtual PC and Virtual Server

One day one of my friend asked me which tool are you using for SharePoint development, Is It Virtual PC or Virtual Server?

I told him, hmmm, till now I am using Microsoft Virtual PC 2007 but I thought that let me find out what is difference between Microsoft Virtual PC and Virtual Server, after doing some research I have found out that basically Virtual PC is designed for desktop PC in which Windows XP operating systems running and Virtual Server designed for server PC in which Windows Server 2003/2007 or any server operating systems running.

Another main difference I have found was, in Virtual PC we can’t connect or access one Virtual PC to another PC, but if we have Virtual Server setup into our LAN then we can connect and access all Virtual Servers.

Extensions for Virtual PC files:

Virtual machine configuration files are .VMC files,
Virtual hard disk files are .VHD files
Virtual PC saved state files are .VSV files
