On the original topic. The whole idea makes me laugh. There is no way anyone driving with a mouse is going to be faster than I am with a keyboard. Navigating the filesystem, manipulating the filesystem, editing text esp. is laughable (I love VIM and nothing can come close to the speed I can edit in VIM, esp. not anything you have to drive with a mouse). Very few applications are better done with a mouse/pad (like Photo editing in Photoshop, but even there various keyboard shortcuts are faster than navigating submenus).
