more correctly the itouch uses a capacitive screen that reacts to the 
change in voltage when skin, or something with similar conductivity, 
comes into contact or very near.

this then allows the ease of gesturing and other stuff we see in the 
interface of said device, as one do not have to maintain a minimum level 
of pressure on the surface of the screen. said requirements on resistive 
screens, like whats used everywhere else, means that one invoke the 
surface resistance of the finger, the very thing that allows one to hold 
onto something like a glass of water or other apparently smooth surface.

im guessing, but i suspect that the double-press of the tablet screen 
comes from issues with registering no pressure. that is, if you suddenly 
have a drop in pressure followed by a increase, it may register that as 
two presses when it was just a movement of the finger or something of 
that nature.

i would say that the single clever trick they did on the device, and its 
relative, was the selection of said screen.
