Last week I was talking to Andy Malone who has been running some great sessions for us up in Scotland, and he mentioned Virtual PC 2007. Until he mentioned it I didn't know it was to be seen outside a certain privileged circle, but it is; you can sign up for it on the Microsoft Connect site. I'll be installing it later today. Thanks to Ben Armstrong for the info. Ben also has instructions to make Virtual Server work on the Release Candidates of Vista.
