While I agree with your point, and have never had any use for the touch screen on my work laptops and don't miss it now that I don't have it, some colleagues love it. They do many manual things, comparing lists and whatnot (yeah, I know) and they absolutely love being able to directly click things, or scrolling the contents on one side without moving the mouse pointer from the other. I think the point is that this opens new avenues of interaction with the machine. Of course, there is the risk that things would get overly adapted to touch interactions (even more white space, giant buttons, etc), which I'd hate.
