Does this handwriting - http://i.imgur.com/46zsYWw.png - look like a device that's picking up fine, fast movements as well as paper? Or this - http://i.imgur.com/BEvjRWI.png - what are those highlighted shapes? It's possibly just the chap's handwriting, but in a product video for a new product all about how it's like handwriting on paper, wouldn't it be a plan to choose someone with tidy handwriting? But I don't think it is his handwriting; in both of the bits pictured there's lots of uuuuu shapes and round o shapes are mashed or almost missing; 'Let A be ev°n uhon Z is .dd. P l o t roills OK Kincticn'.
Put their video[1] in 0.25x slow motion and watch at 39 seconds, the 's' they write at the end of 'Restrictions', see it gets the start and end missed and the shape distorted. Then watch the filling in sketching movements at 40 seconds, the ink appearing lags by the entire length of the pen stroke...
Yet in a couple of places, it looks like it is keeping up with writing. Where they say it's the fastest, where they zoom in on his handwriting.
I want it to be paper. But ... I dunno...
