Honestly I think this is a bit of an overreaction. Using myself as an example, playing audio while maxing out my quad core CPU led to a CPU temperature of about 60-65C. This is well within the operational parameters, and I'm not at all concerned about any loss of my Mac Pro's useful life. By the time my Mac Pro's CPU fails, it will probably have been sold two or three times.
As far as loss of productivity is concerned, can you provide actual examples of lost revenue? This is an impossible case to make against Apple.
I absolutely agree with you !
End of the story, they solved the problem, with a software patch, so the machine wasn't flawed.
