Yeah... It appears that the physical objects have an unique fingerprint that is recognizable by the software.... I could see that being a puck on a CAD or drafting system.
I would buy that instantly if you could run Final Cut Pro X on it -- there are some things you can do better by getting your "hands dirty" -- rather than through the indirection of a mouse and keyboard. I also like the ability to work standing or sitting as your mood/need arises.
I used to work with a sound engineer in post who had a touch controller. That was at least 15 years ago! I think touch is much more intuitive than a mouse or a track pad. As you know from editing, before computers there was video and before that it was very physical - the original 'touch'. The problem with touch and the the 'tired arm' syndrome has perhaps more to do with repetitive strain than 'tired arm'. Some people use Steinbeck style controllers... ;)
