Virtual PC is an essential tool.  MS is supporting it very well. The product manager @ MS stated that soon VPC will be able to import WMWare images.  This would be a great advantage to VPC over WMWare.  In using VPC, I have used the newsgroup for several questions; it is one of the most active newsgroups I track from MS.  Most of those questions have directed me to either Robert Moir’s Website or this website which is itself running in Virtual Server!  People are using VPC in ways I never imagined!  They are using it with ghost to convert from WMWare images today!  This is a great product even thought shared drives do not yet work with Longhorn L.
