That's utter nonsense. Apple is below 5% market share worldwide. They are a nice customer for Intel, but sure not someone to dictate their roadmap.
This is mobile. Apple has a higher share in mobile than in desktops. Apple also has a very high share in the premium notebook market where Intel gets to make higher profits on more advanced chips. Apple also has a history of making the market go in its direction, so if Apple wants lower power now, the entire market will be wanting it soon. Intel will miss the boat by not giving into Apple's request.
Intel has previously bent to Apple's requests too. The low-profile packaging for the original MacBook Air had been explored by Intel, but it was sitting on the shelf. Apple asked that it be revived and completed for an ultra thin form factor laptop. Apple has also gotten first dibs on high-end processors for the Mac Pro. And, of course, Apple is Intel's to-market partner in Thunderbolt, Intel's main hope for public adoption of the technology.
Intel has much reason to listen to its larger partner, Apple.
