Yeah that's pretty unique, I've never heard of a capacitive touch screen that supports a (conductive/passive) stylus and has so many extra features:
Angle of touch, can be used to determine which hand is touching
Proximity Channel, can have a hover event when you're about to touch
It has a good chance of showing up on any Medfield-based final devices, at least. It's also used in the samsung galaxy tab and Samsung Wave.
