Well, choosing the wrong component is voluntary ;-)

I suppose the more components in a device the more chance there
is that one will fail. But it doesn't necessarily mean that one WILL
fail. There are obviously connections within a circuit, but a resistor
in one part of the circuit probably won't influence the failure rate of
a resistor way over the other side of the board. A domino effect is
always a possiblity

You might have a stereo or car that goes for years and years but
a brand new one may have troubles right from the beginning and
never be completely right

You'd have to put a figure to how long is long enough to be value
for money. If your 50 year old black and white TV broke down
today and had had very little service money spent on it, even if it
cost a small fortune to purchase, you know it was a good buy. But
it's broken down at a time when technology has moved on to bigger
and brighter things, so it may not be a great loss
