It looks pretty cool. And if it is only $200, that's cheap enough for me to consider picking up as a supplementary device.

I do wonder about how responsive it will actually be in use, though. The video is in some spots animated and in some spots played in fast-forward. It doesn't show any actual use of the device to get a sense for how zippy it is. If you watch the video on YouTube, there are some related Chinese videos that show up that show a little bit more (still not enough to be confident about speed) but some features like hooking it up to a monitor and using it like an input tablet.

Thanks for posting C.O. I'm curious to see how this product fares.
