I'll agree to a certain extent-- you see a lot of 10+ year old Linear
supplies working just dandy now, but dead PC switching supplies seem
pretty common.
*However*...
It's been my experience that when a switching power supply dies it
seldom harms the electronics it's attached to-- that's not a safe bet
with linear supplies. Switchers tend to lose power on all rails at
once, but many switching designs can drop just one voltage and keep the
rest going. That *can* cause damage on a lot of designs...
