Using Ubuntu Linux, I really miss the little desktops in the right corner. The ones that allow you to switch between multiple desktops. Unfortunately, Vista did not ship with one. Therefore, I had to go search for one.
I first tried VirtuaWin, but I could not figure out how to get it working. Then I tried Virtual Dimension. It is not exactly like Ubuntu, but it is pretty good. Therefore, that is the one I am sticking with. The developer seem to have stopped working on Virtual Dimension in 2005, but it does what I want it to.
So if you are looking for virtual desktops like Ubuntu for Vista, Virtual Dimension does the job.
