>I suspect it goes the other way, too: touch friendly apps won't feel right with a mouse.

That's the angle I'm looking at it from too. Why should I install this on my non-touchscreen Thinkpad? Will I need to constantly 'flick' and scroll things with my Trackpoint?

From the video: "[The apps] are designed for touch... but of course they work well with mouse and keyboard as well if that's what you have."

Sorry, but that's not how it works. Microsoft needs to realize this. Everything he was doing there would be terrible with a mouse.
