Why do you say that? I think this is an unreasonable thing to say. To start, this has nothing do to with a particular application. I simply want to be able to move the mouse without actually dragging it. How is that "acting not as a touchscreen"? A touchscreen "acts" by being touched. That's the definition of a touchscreen. And I could even admit that a common assumption is an absolute mapping. But that's about it. All that this would do is further generalize and unify touchpads and touchscreens - step that is long due, if you ask me. But well, I don't want to advance some philosophical argument: This is practically relevant and a reasonable thing to like.
