Wacom Pen Touch display - Possible great tool to use in ardour

Just seen this popp up on my facebook page.

Basically its a portable touch display using a pen, like whats used by graphics artist.

The guy in the video demonstrates it being used in cubase and apart from a couple of minor flaws looks like a much more productive way of working instead of using a mouse.

Dont know if it works in linux as havnt looked further into it yet.

But i think it would be great to have this. Personaly i would have it as a 2nd display for the editor window, infact it would be cool to be able to use 2 of these as dual screens and have an editor window and mixer window, just wonder if 1 pen could be used across 2 displays
