"Taste" is certainly the key word; each to his own, but be careful here.
With respect to the Mouse Systems optical mouse (same as on DG AViiONs too),
what happens is, if you angle the mouse (less than 45 degrees wrt the pad),
then move the mouse straight along its axis, the cursor moves at an angle
across the screen.  In other words, the output does not care what angle
(up to 45 degrees) you are holding the mouse at; the pad axes take precedence.
Now if this is what you want, fine.  But for my taste, I want the cursor to
track along the mouse axes.  The doggone pad is always getting cocked, which
makes the mouse go crooked until you move the pad back.  So I taped the pad
to the desk... now there's a permanent part of the desk usable *only* by
the mouse.  Grr.
