It looks interesting, and the the palm rejection is probably the feature that will make or break it. It looked to me from the video that nobody was actually resting their palm on the surface - they either suspended their hands above the screen, or wrote on the edge and rested their palm on the (ipad's large) bezel.

So perhaps, as of yet, that 'tricky problem' isn't quite as solved as they say it is.

The Collusion guys are hanging out at my coworking space(fishburners). I just used it 5 mins ago. The palm rejection works great.

Yeah, palm rejection is better than anything else because they simply don't register iPad touch events when the pen's pressure sensor is activated.

The underlying tech is that the pen is an ultrasound transmitter and the attachment has stereo microphones. It's then just a matter of basic trigonometry to get the position much more accurately than the iPad can detect a finger.

That's bad ass

Thanks man! what's even more badass is that the core IP around the ultrasonic techniques used in the pen was developed by the Israeli Military. Now that is BAD ASS!
