[PLUG] OT (Hardware): Do pointy devices wear out?

[Rich Shepard]

  My good ol' Kensington Orbit trackball is acting balky. I've castrated it
and checked for impacted threads and the usual culprits that cause it to
drag and jump instead of smoothly tracking across the screen. Nothing there
that I haven't cleaned out. I just put some alcohol on the two rollers in
case they had warn smooth.

  Could these devices just plumb wear out? I've had this guy for at least
5.5 years and it's really nice to use. But, trying to do fine movements when
creating illustrations in tgif is an exercise in frustration because of the
jumpy movements.

Any thoughts?

Rich
