It seems that the most widespread drawback with light pens is the
grueling effort it takes to use them.  However, it also seems that
that impression is often promulgated by non-light pen users.  Now
I personally don't care much for light pens, but I know of an interesting
situation where a BIG user of graphics had to decide whether or not
to switch to data tablets instead of light pens.  The company
(McDonnell Douglas in St. Louis) had been using the IBM 2250s and
3250s and wanted to upgrade and decided on E & S hardware.  BUT, E & S
did not offer light pens at the time for that hardware.  The users
took a vote and said that they WANTED light pens--not tablets.  As a
result, E & S developed light pens for that hardware.  That was a couple
of years ago, but I suspect McDD people still prefer the light pens.
I think the subject is almost like discussing one's favorite color....
