You're talking about a company whose motto is "only the paranoid survive". Why win when you can utterly dominate?
They only started caring about power consumption when it was already obvious to everyone that ARM is going to pose a threat to them eventually. I think if everyone sees something that's by definition not "paranoia". To be paranoid, you have to see and believe something before others see it.

I'm being a bit pedantic, but it seems to me they refocused on power consumption beginning with the launch of the Pentium M (forerunner of the Core and Core 2 lines) which was released in 2003 and was surely in development several years before that.Or do you think they were thinking ahead to ARM already in ~2001 or so? Maybe they were... although I think they were thinking about targeting laptop sales in general at that point, not ARM specifically.
