Marketing. I saw a washing machine that was advertised as having
"crystal control". Presumably, it timed its wash cycles to one part in
10^9.

Jeez. I haven't run into that one in person, but it wouldn't surprise

toy lenses is a very similar problem.

Reminds me of DVM's with 3 1/2 digit readouts and 1% accuracy. The last

Exactly. And don't get me started on the low ohms ranges of those meters...
