Yes, yes, YES.  Both Tektronix and Hewlett Packard have burdened
users of their test instruments with touch screens.  And yes, your
arm gets darn tired.  Also, after a couple of hours of use, the
screen is so dirty and greasy from all those finger presses, that you
can barely read it anymore.  Touch screens that are meant to be both
touched and read, are a big lose.  Even those parts of the screen
that don't have touch buttons get greasy from bracing your hands.

Touch might be interesting as a replacement for a digitizing tablet,
though.
