How do we know the number of hardware design errors? With IA32, it's easier to discover these problems because the CPU is used by many people under many operating systems. IBM designs the OS and CPU, making it much easier to cover up any problems that do exist.

It has always amazed me that IBM is able to put out a new processor every year or two with little or no hardware logic errors. I know from articles in the technical journals that they do extensive testing, but heck, in the software industry, we do extensive testing and we STILL have to put out a significant number of fixes.
