Rather, it has a low profile designed to be guided by your fingertips instead of your palm. That way, the white surface is cleared off your palm allowing your finger tips access to it's multi touch surface for various gestures. Once you get used to the mouse being a "fingertip controlled" mouse instead of a "palm controlled" mouse, it performs exceedingly well.
