Buying Back Stocks or Dividend doesn't do any good for Apple, Apart from its shareholders.

I am thinking on Worldwide Data Carrier Network. But Apple doesn't own ANY frequency spectrum. And there isn't a single worldwide common Whitespace for them to use.

Buying Intel isn't out of reach. You only need 51% of Intel Stocks. And Apple can afford that. IT fits them in many ways. And i think Intel is pretty cheap for its price in terms of investment.

Although i doubt that is realistically possible.
