Resistive touchscreens do have the eqivalent of a mechanical part:
the material between the front and back surfaces.  When you press, you
push it out of the way to make contact.  This wears down over time; I
actually kept my first Palm Pilot long enough to wear the screen out
(and was able to find a replacement screen on ebay, so it kept on
going for several more years!)
