Multiple desktops on Windows

I've never been able to find a decent piece of Software that would give you multiple Desktops on Windows. Any *NIX person just can't leave without them... I've tried the Windows PowerToy and another one (whose name I don't remember ATM), and both sucked..the whole desktop would stop being responsive and the general experience was just horrible. By pure accident I stumbled into VirtuaWin and I must say it's actually working quite fine for me. Thanks Johan ;)
