Anyway, lets talk about what it is. It is a simple USB attached sensor that pops right onto the top of your laptop or desktop screen. Then you utilize a provided pen and Viola you have a tablet laptop. Granted its not as accurate, but its pretty darn close. Better yet, all the tablet options available in Microsoft products are immediately recognized. It works as if the pen replaces the mouse. This is a much better alternative for training your expert. You would no longer have to lug down the big Touchscreen monitor. Instead, you could just bring your laptop with the Duo attachment.
It is just a nice added fix that is well-priced. Enjoy the info.
