Besides stockholders to answer to, there is also the ARM stampede to battle. Using that tired old meme of intel not have any competition to explain intelss execution problemss has gotten ridiculous.
Since 2006 Intel has delivered four architectures and three process nodes, more than anyone in the industry, with only minor delays. More important, they are ahead of the curve, which means that whatever problems they have they don't have anywhere to look but themselves to find a solution.
That's a stark contrast with Nvidia Fermi woes, or AMD/GFL 32nm snafu, or IBM late introduction of their 32nm node, or Sun's Rock architecture. But some people seem to have one standard when judging Intel execution and another to judge the rest of the market execution.
