One point that I havent seen mentioned about light pens yet is 
that they only work when you have light on the screen. 
This means that they can only point to bright objects on the screen,
and can not draw on a totally blank screen. This may not be too 
much of a problem if you happen to like black characters on a white 
background, but is significant for general graphics work.
 The other general problem with light pens is that unlike mice or
tablet puck they dont stay where you leave them, they must be moved
from a rest position to an active position for every use.
