One thing I really like about this tech: the ability to discern stylus vs. hand input. This is useful when resting a hand on the display (as sometimes is the case for the N810) but not wanting it to affect the drawing in any way. Perhaps not necessary, but can improve interaction greatly for non-portrait input.

With the N810s pressure gauging, I wonder if this can currently be emulated in software, with special input libraries and a little extra computation. Perhaps simply to shut down the input when the pressure (size of input tip) passes a limiting point. This ensures our drawing comes from the pen tip and not our palms....

YARR!
