Yes, in the Synergy Touch post, there is a Modbook Pro video which includes a demonstration of Synergy Touch. The demo runs from 2:08 to 6:00, roughly the middle third of the video.
Also, there is a video demonstration at vimeo. In that video, the Synergy Touch part is from 10:25 through 13:57.
Both of these videos date from January of 2009. So there is no telling if this is really what we are going to get.
