As others have already mentioned, those machines would probably have died
even without Prime95. The way I have always looked at it, Prime95 generally
causes those types of (pre-existing) problems to manifest  _before_  the
warranty expires, rather than after. This feature is certainly not a Bad
Thing :-)
