Looking at the web site and the graphics used on the images I would think think is NoteSlate under a new name. That gives me pause to begin with. Secondly anyone that thinks this is going to be a better writing experience than an Ipad Pro, Surface Pro etc needs to watch the video again an understand that it will be less than that. They do a good job at first blush of hiding the lag but it's definitely there. It just doesnt have the processing power to do better.
I do applaud them for finding a new/better display stack to use. Unfortunately it comes at a cost.
edit- slightly improving my opinion is that they are working with these folks
https://www.dragoninnovation.com/team who I know are very professional in what they do.
