"Actually, it tends to be a bathtub curve.  You tend to see a cluster of
"initial "infant mortality" failures in the first few hours or days, then
"very few failures for 10 years or so, then they start dropping off.

this would generally support the scrap-and-replace approach rather
than repair.  after infant mortality [presumably mostly covered by
warrantee], by the time you had significant failure the stuff would be
horribly obsolete and ready for rescue...
