This particular panel is optical touch - inside the bezel it has IR projectors at the top and sensors on the bottom. It is not as good as a capacitative panel, but far, far better than resistive ones. One reason I like the ASUS Transformer is that it shows, IMO, that touch and keyboard/mouse can be complimentary. As prices continue to fall and touch becomes ubiquitous, I think we'll see more and more of these. Ergonimics can also go a long way - a large monitor that's sitting at a ~25 degree angle will likely eliminate the bulk of the "gorilla arm" problem.
