Surprisingly there is still not a native virtual desktop feature in Windows. There are various third party apps that will do the same thing, and XP had an unofficial powertoy that MS made, but nothing built in yet. Always struck me as sort of a poor man's multiple monitor solution, but it can be useful. I've never really gotten into the groove of using it, but I think that's because I'm just used to not having it as a feature.
Do you 'nix guys use it a lot? Does Mac have something like it?
Yes, it's called "Spaces" on a Mac. I've used it on occasion, with a full screen xp vm on one of the spaces to switch back and forth from xp and os x.
