Dean's comment:
I know that you are frustrated with this discussion because it
will go nowhere, but there is evidence to support the potential
problem of turning on and off a computer, and I will bet that
you will remember it.
About fifteen years ago, Apple Computer brought out a new model
(the "Lisa", I think) that had many problems. One of the problems
that I recall was that the motherboard heated and flexed somewhat.
This happened repeatedly and on many computers some of the
chips would eventually work their way loose.
I would imagine that traces might break and solder joints might come
loose under the same circumstances. (board flexing)
But, the real, clear danger from leaving a computer on all the time
still remains the increased exposure to power line surges, and
we have heard people give anecdotal evidence to that danger
in this list just a few months ago.
