For gaming, mostly agree. Although I think that the pretty graphics are mostly for show, the real power will be the ability to customize gestures for any application, and the utility you get out of these gestures can well be worth looking down at a "mouse screen."

I'm imagining being able to manipulate a CAD model in isolation, freely rotating items in PowerPoint, redistributing power among throttle/lasers/shields using sliding bars (X-wing, anyone?)...I'm sure there are many more.

I'd almost argue to keep a normal track pad for dedicated cursor navigation and have the awesome set of touchscreens as a peripheral. Then have an amazing API for software developers to do creative things with it, and have an amazing UI for the layman to create their own mappings. That might get adoption for this type of thing going faster.
