I would guess that 52 pc's a day, out of 10,000 is not that high if they are using generic pc parts under high stress loads. Probably, alot of hard drive failures. Also, if they don't stress-test the new parts they put them in, part of that .000052 is just bad components to begin with.
How many "bad returns" is typical for pc parts?
I hope that.... because if not it's a high rate of pc failure. Very high! The correct number is 0.0052:-) If you assume a constant rate of failure, they would have to replace all computers in a very short time: about 192 days. Even if you cut it to half, assuming that many pc comes already broken, you find that they replace all computer in 384 days. That looks very expensive, and I am worrying for my poor old pcs:-( Praise
