Remember that the touchpad is dual-mode. It has capacitive and
resistive parts. The center is both capacitive _and_ resistive, while
the outer parts are resistive only. That means you can use _any_ hard
object (though not a sharp one!!) like a fingernail or a stick or a
wooden dowel to draw on the large area of the touchpad. That's the
mechanism that takes the place of a touchscreen display, and one that
also accomodates writing in languages that cannot be correctly
represented on a keyboard (japanese, chinese, thai, etc).
The resistive part also uses absolute positioning, just like a
