Why? Perhaps you need that kind of precision editing images, but I'm
selecting controls & menuItems, dragging objects, inputting ink to
text, and placing an insertion point in text. None of that requires
repositioning the cursor at the exact pixel location it occupied previously.

I did so yesterday. From 8AM to 6PM, + two hours later, I was
working on a new Rev app--with my keyboard in a drawer. My writing
hand was less cramped than it would have been if I had been using the
mouse all day.
Ever since written language was invented, some segment of the
population has spent a major part of their working day with a pen or
pencil in their hand. Was carpel tunnel syndrome known to mankind
before there was a mouse?
Note I didn't write "don't try to move your hand", but "see how much
of your screen real estate you can reach with a pen without moving
your hand." Of course I move my hand! My point is I can move it
more quickly and shorter distances to accomplish the same task with a
pen than a mouse.
Over the years I have used mice, trackpads,and trackballs, and IMO
the pen is mightier than the mouse.
