Yes. Some touch screens emulate a mouse, and can be
plugged right into the PS/2 mouse port. You 'tap' the
screen (usually with a stylus) to 'click'. My old
Palmax mini notebook operated like that. Also, you
can buy overlays from many places. I believe there
are other types of touch screens that do not emulate
mouse, and some can be switched to different modes
of operation. The overlays typically comes in sizes
from 6.4" to 15". The StrongARM and X-Scale processors
have touch screen capability built into the chip. I
have forgotten who the companies are that sell the
touch screen overlays, but they can't be hard to
find with google search. There are also some small
text/graphics LCDs with built-in touch screens.
