I would certainly use this. I will also buy it if it supports linux out of the box.

When I first saw the Dave2D video on Youtube a couple of days ago, I thought it would be a useless feature, but on further consideration, I'd totally use it.

I have an Zenbook ux501 that runs on wired power most of the time anyways so battery life isn't a concern for me personally, but I'd use that touchscreen as a security cam monitor, system resource monitor or some type of dashboard. I use a mouse most of the time anyways, so most laptop touchpads are useless to me.

I'd love a second Mon for everything from man pages to a screen for a soccer game. I use mostly key bindings so it wouldn't be too much for me.
