I'm finally using beryl on my main machine, and its beautiful. I'd been using it on and off, but now I have it turned on all the time. Despite being really beautiful it really does provide a boost in productivity. Especially when coding. Try F8 or F9, and see if it helps you too...
Ok, I'll tell you what F8/F9 does. Its Linux equivalent for OS X's expose. I really like the feature since it makes it much more easier to work with open windows/workspaces.
