can i assume the device being able to ignore you resting your hand on the screen when drawing/writing with the Pencil is a software driven thing and not a hardware limitation? in the video demos to date they seem to show both hand hovering above the screen and hand sitting on the screen. if it's a software thing then no issues, devs will accommodate this. if its a hardware issue then drawing or writing with your hand hovering will be quite an issue. i'm assuming it's similar to the telephone app that recognizes your ear against the glass.
