Another friend, Ryan Stern, pointed me to this application, Virtue Desktops — a third-party application that will create virtual desktops on your Mac without making you wait for Spaces to be released this spring.
Having used virtual desktops on KDE on my Mac, I found that it wasn’t such a big deal. But being able to drag and drop applications into desktops may make me a convert. I’m definitely interested.

I've been using VirtueDesktops for a while now, and I love it. It's great to see Apple finally implenting this feature themselves.
