Well, there was the Intel Larrabee project, which was killed before it 
ever went into production, which set Intel back some.


And I'm sure there was some arrogance in this mix, also. I bet Intel 
figured they could be late to the game, and still win, because they're 
Intel, or would just use the same tactics that they used to crush AMD 
once the Nehalem processor came out. They were late that party, too, but 
still won.
