I agree, a touch-screen on a 'pro' laptop (unless it's a 2-in-1) is useless.
Also: Please don't ever, ever touch my laptop's screen.

You could easily see my swipe or pin pattern from prints and smudges, even from one use, which never happened with actual keys.
Same kind of people leave the plastic wrap around their remote controls (or worse, car seats).
The Surface is plugged into a dock for all my heavy work, so I'm not using the screen anyway. If I am using it as a laptop for more internet-browsing related work, the touchscreen is so useful that I don't need a mouse.
