I was referred to this program by a friend when I mentioned that I was using Codec Virtual Desktop, and let me tell you now...between the ease of use and the gorgeous little features, I must say that I quickly changed over to this application. I mean, the transitions are beutiful beween the desktops are gorgeous, and, from what I can tell, barely effect the CPU at all. The features are a bit minimalistic, and, like the last reviewer, I too would like the feature to have certain applications always open up on their given desktops. Another nice feature would be the ability to arrange the desktops in various shapes, instead of just in a linear formation. Despite those two downsides though, the thing runs quickly, quietly, easily, beautifully, and best of all, it's free. A great contribution. Download it as soon as you can.
