I hate cables. There, I have finally managed to start the article. But getting back to the cables, I have a mouse, which connects to my computer. Fair enough: that's a worthy cause for a cable. But then I got a second computer. Now what do I do? Just use the touchpad on one? Or do I get a second mouse and make my desk even more cluttered? A better option would be to have the mouse shared between the two computers.
I think it is fair to say that the Desktop Cube has been one of Linux's iconic features. The cube provided both an easy way to visualise workspaces as well as a nice bit of eye-candy when using it.
