"How many CPUs have you owned?" Another issue as an end user is I don't have the resources to prove that it was the CPU a lot of the time. I've had some laptop failures that could have been the CPU, could have been the motherboard, could have been the power supply, dunno, all I've really got is that it doesn't boot and I don't have the capacity to diagnose it due to the level of integration and inability to get replacement parts to even try to diagnose the problem. And while as a poor college student, I had the time and desire to carefully replace parts and exert maximum diagnostic effort to figure out exactly what is wrong because I can't just buy a new complete setup, not everyone goes to this level of effort, and they may not be correct. End users really can't pick up on these trends. The data set is so noisy. Sure, the "end users" may have had suspicions about this but I've also seen communities come to consensus about certain things being broken that I had very good reason to believe were wrong and were just internet forums amplifying random loud voices being confidently and loudly wrong about things until it become "common consensus" through the power of nothing but the confident and loud error.
