Selling chips for mobile phones doesn't cannibalizes intel's business. Selling chips for tablets might, but at this point in time it would be very risky to think in such a way, and they know this very well. So why hasn't they given their top game for this fight, i.e. offering 22nm mobile/tablet chips ? I think it's because their 22nm is expensive and not very fit to manufacture cheap chips. From what i read, their 22nm tech costs 30%-40% more than using TSMC 28nm (for manufacturing the same parts). Maybe their rising investment in fabs is due to this problem. Another explanation would be that they are planning a coordinated attack: better atom and an LTE chip using a 14nm process. That combination might let them seriously decrease power over competitors. And doing that in bang has strategic value of creating pressure/fear over mobile handset makers and carriers to accept their new design, or be left out.
