When I switched to OS X, it took me a long time to get used to not having virtual desktops. Eventually having a big pile of windows seemed normal. I used Cmd-Tab, the Dock, and Exposé, and it worked well enough.
As soon as I installed Desktop Manager I was sold on it. There are some glitches–mostly related to off-screen windows having the focus–but nothing that seriously gets in the way. It’s GPL’d, too, which is a treat in the Mac culture of shareware everything.
My menu bar is getting crowded.
