I think the point is that you can have everything tidy in "Tidy Stacks" but have the docs you are working on scattererd around however you like. Its just easier and quicker to flip to a stack and pull out an additional document. The current Windows Desktop isn't very usable, its just another folder with some unique "always open" attributes. Imagine everything being filed away as normal, just with this application replacing the desktop - the active work area - I think it would be great!!
