Certainly getting into mobile would have taught them how to compete in a very different market with lower margins and that would have put them in a better position today. Intel was addicted to the easy money of the Wintel days and has had a hard time transitioning. Otellini's decision to not supply Apple with cpus for the iPhone was a huge mistake. (I seem to recall that the calculations to determine that it wouldn't be profitable might even have been based on a mistake in a spreadsheet, but that's probably apocryphal)
