a friend of mine tried litestep, just because he thought it was cool. But he never actually took the time to set ANYTHING up, and i would constantly be asked how to do stuff.
If you're gonna use one, you should know regular win98 INSIDE OUT. As in 3 different ways to do any given task. After that you can go to say litestep. You must spend a lot of time configureing it, and constantly tweak it to your liking. Once you get it all setup and know what you're doing, its really cool, and you'll get addicted to the desktops and the really flexible icon's.
