Yea, it's the same trap that Win Media Center fell into. 2-feet mode versus couch mode. Though touch is different. The largest segment of computers from what I understand are laptops. If these laptops are fitted with a MacBook Pros style touchpad that would be sensitive as iPads, it could introduce a whole new dynamic that we can't fully understand until we truly experience it.

For example, imagine a version of Excel that you could do the sum of a set of numbers by speaking "sum up these numbers" and swiping your fingers over the set that you wanted to do the sum on. Excel as it exists today may not be the best user of touch but tomorrow's Excel may provide much smarter ways of getting better milage out of it. It truly will be dependent on how well MS developers can imagine.
