I'd argue there was a fourth serious failure, and that was Intel allowing the motherboard manufacturers to go nuts and run these chips way out of spec by default. Granted, ultimately it was the motherboard manufacturers that did it, but there's really no excuse for what these motherboards were doing by default. Yes, I get the "K" chips are unlocked, but it should be up to the user to choose to overclock their CPU and how they want to go about it. To make matters worse, a lot of these motherboards didn't even have an easy way to put things back into spec - it was up to you to go through all the settings one by one and set them correctly.
