The video on their site[1] shows the pen lifting particles directly to the screen, which would be amazing, if true. I dug around for a while to find out how it works, expecting to find some very clever system for detecting the particles that have risen to the surface, etc... Instead it appears to be just another stylus/display system, with all the downsides that imposes. I could do much better getting a "pen" for my old HP convertable laptop if I wanted that.
