Otellini made a HUGE strategic mistake by allowing Microsft to develop Windows 8 for ARM, and letting them release a #$%$ version of Windows 8 for traditional PCs. This is on top of the Nokia/Meego disaster. Paul O. messed this up bigtime & shareholders will be paying for it for a long time.
Otellini doesn't control Microsoft's actions so he is not responsible for W8's problems nor Windows RT either. Otellini is killing off ARM's RT by doing the only thing he really has control over and that is to make cheaper & better processors that run real W8.
Intel can be blamed for the failure of Meego and should take blame for failing to create the dominant OS for mobile devices. The need for an "Android" like OS was obvious and Intel had the opportunity & resources to do it. But unfortunately Intel didn't act on the idea early enough. By the time Meego was launched, it was too late.
