Why it won't work (Score 1)

In order for someone to use a desktop effectively, the user needs to be able to easily visualize the desktop. The biggest problem with a 3d desktop is trying to visualize programs, documents, and mp3s suspended in space, where there's no gravity. If you put gravity, bookshelves, and a desk in 3d, it has a better chance of becoming accepted. For now, though, looking "down" on my 2d desktop is the only way to go!
