that's pretty amazing IF they can reduce the cost compared to other similar technology. Wacom has something similar but for a 21 inch, it's around 2500$.

I know theres still the pen but ya know? who wants to get a 3000$ or more screen ? unless it comes with the whole interface(computer-HD, soundcard, etc..).
but if it accepts anything on it, i will be very interested!
