  Currently, there's nothing better than mice. 
 Real keyboards! 
 
  For pixel-accurate pointing on a CAD drawing? 
 I am given to understand that some CAD systems let you input
 coordinates numerically. So, yes, in principle! 
Well, yes, in principle.  It's not *efficient*, but it is available.
Sometimes, it's even the right thing to do; in board layout, I typically
numerically position the board outlines because they usually have to fit
a numerically-specified mechanical drawing.  If I had to do that for all
the components on the board, though, I'd go mad, and it's fairly easy to
do pixel-exact placement when you're just lining things up (assuming you
have standard ~72dpi pixels; these newer "retina" displays change that a
bit).
