What's with wall warts? Do they have a five year warranty clock
built-in?

I just lost the third wall wart in a month.

All of them 5+ years old, or more, so I guess I can't complain.

What's to wear out... capacitors?

This one was for my Cisco BEFSR81 Router. I think it's actually a lot
older than 5 years.

I'm presently up and running on a bench supply :-}

Caps, and switching supplies can have the startup resistor or the
semis die. Also the RoHS solder joints and Chinese assembly may not be
so great.
