$10 US for a conventional mouse versus $40 for an optical. That's a difference equal to roughly seven sets of guitar strings. I need guitar strings worse than I need faster, smoother, lint-free mousing.

And what I did today was the same thing I do every day (or so it seems): Cut up fallen trees, put tree pieces in truck, drive truck down driveway to road, unload tree pieces onto shoulder of road making already huge pile even larger, cuss hurricanes, drive truck back up driveway, repeat.
