I've been using Desktop Manager on my iBook to get Virtual Desktops going on OS X but it's been suffering a bit since Tiger came out, you have to use their Alpha release which is dodgy to say the least.
Most annoyingly it doesn't always save preferences, so I use command-f1 to get to desktop 1 etc, but this setting does not save, so each time I reboot I have to manually reconfigure the whole thing. I could stand it and wait for a fix when the alternatives was a $50 product from somewhere.
Now however the wonderful people at You Software has a promotion on their product You Control: Desktops so instead of the usual $30 it's now $10. I do not know how long this offer is for, it certainly isn't well published or anything.
I bought a copy of the software and am using it at work and home - the license allows for multiple installs as long as only one is being used at a time - and am very happy with it, does nearly all I would want. I'd strongly recommend it, you can't go wrong at that price!
