I think you got it right. My proposal was definitely not meant to be the end of the conversation. Much rather the beginning. I'm sure there are huge opportunities in exploring a more diverse set of input mechanisms (and their combination).

In this case, I'm simply trying to make a point that touch screens can be more control panels with buttons and sliders on them.

Oh yes, and I feel you made that point. It's just my hope that you (and/or others) keep moving the conversation forward :).
