Why do you consider these to be mutually exclusive forms of input? Just because you can touch a screen doesn't mean that all other forms of input are no longer applicable.

I don't.

I do think the ergonometrics of using touch on a large(ish) vertical display - "Gorilla Arm"[1] - is a deal breaker for extended interaction.
