Do you have any idea how much work it would take to get a touch screen 
into a calc?  Besides, they have to have their own processors and 
software to run. (they would have to communicate with the calc using 
digital I/O's.  This means that it would probably have to be external 
and have some giant driver to run it.  The point is, unless they've 
figure out a way to shrink an electronic circuitry 2 inches thick down 
to some thing manageable, it ain't going to happen.  Also, they take a 
lot of power.

Well, sorry if I burst your bubble, but I know this stuff cause my dad 
works with them all the time.
