hard to tell exactly what actuarial voodoo they do.  I noticed AMD's 
cpus are waranteed for 3 years.  whether they shave the tolerances 
by recognizing that lots of cpus are used for shorter lives, or at 
low duty cycle, we can only guess.  I suspect companies are pretty 
conservative when evaluating this kind of risk, as loss of reputation
is considered a very high cost.  (or rather the gaining of a bad rep.)
