They do. And how do you think that stylus works? Touch screen! and one 
of the most rudimentary types, too! (Because the more advanced 
capacitative touch screens won't work with a plastic stylus.. but the 
ones built of a grid of embedded lines work just fine with the stylus, 
but are rather inconvenient because they have flexible layers, can wear 
easily, and somewhat obscure the screen due to their design, if you look 
closely, you can see the little dots that act as standoffs between the 
grid points)

An exception to the touch-screen stylus idea is something like a Wacom 
tablet, which uses an inductive system (similar to RFID) but, those have 
been around for ages ....
