I don't want to touch my screen, I hate finger prints on my screen.

Now if the screen was on a touch pad, or a mouse pad, that always showed the metro tiles screen so you always had 1 press access to applications, that would be sweet.
I would love it if it were by my hand, always displayed so I could quickly tap applications. The tiles would never disappear, the win32 apps would show on another screen, I could then fire off multiple programs in quick succession.
