I use Air Display (app that lets you use an iPad as an external monitor, and to control that monitor w/ touch or the mouse) on a regular basis, mostly just as a chat window next to my MacBook so Adium isn't taking up valuable screen real estate, and I often find myself touching the iPad to move windows around, close pop-up notifications, etc... and then I find myself trying to touch my MacBook screen without thinking to do the same thing, and disappointed when it doesn't work. So I can totally see usecases for a touch laptop - it feels like the natural next step, plus you could do things like draw directly (with a stylus) in Photoshop instead of using a graphics tablet.
