move over capacitive/resistive stylii (?)

maybe i'm just a geek, but I find this technology amazing. I'm a little bummed the the touchpad doesn't include stylus support for the ultimate notetaking/drawing experience. But this new technology would allow any device (as long as it's powerful enough) to interpret input from the pen.

I'm not sure about the hardware requirements or availability, but i'd love to see this tech implemented in future devices.
