I use it vanilla and it's great with keyboard and mouse. I don't know why you think it was "designed for touch screen" though. Is it because of the tiles? Windows always had tiles... what do you think desktop shortcuts are?
The Metro UI was designed for touch screens. Windows 8 will lead to most if not all desktop/laptop systems having touch screens and a significant portion of the Windows 8 ready systems have touch screens.
