> Fun fact: Bob Colwell (chief architect of the Pentium Pro through Pentium 4) recently revealed that the Pentium 4 had its own 64-bit extension to x86 that would have beaten AMD64 to market by several years, but management forced him to disable it because they were worried that it would cannibalize IA64 sales. File this one under "we made the right decision based on everything we knew at the time." It's really sad because the absolute right choice would have been to extend x86 and let it duke it out with Itanium. Intel would win either way and the competition would have been even more on the back heel. So easy to see that decades later...
