While I find its inclusion to be a pointless gimmick, I'd like to point out that this chip does not increase your phone's ability to do surveillance. It's going to have much poorer reach and performance than, say, the front-facing camera. The benefit of such a device is mainly that it's much better at distinguishing gestures in 3D space, regardless of lighting.
