Performance has flattened out due to power limits. Even in a hypothetical world where smartphones and tablets did not exist, Intel would still be facing a problem competing with itself if the next generation of chips offers little performance over the previous generation.
Humm, I politely beg to differ. I think INTC long term prospects are being built right now. INTC is in extreme build out mode- Where the heck has everybody been? INTC is investing billions for something... I can't believe that INTC would just throw some 7 billion dollars in new fabs and expansion projects to just try to whither out a flatlining PC market segment. I think the there are several large customers looking very seriously at INTC as a foundry. Not to mention eating ARMS lunch from the bottom up.
