The famous PBS commentator Robert X. Cringely has come up with the theory that Apple's decision to use Intel processors is nothing less than an attempt to dethrone Microsoft.
This is what he says:
OS X 10.4 – Tiger – is a 64-bit OS, remember, yet Intel's 64-bit chips – Xeon and Itanium – are high buck items aimed at servers, not iMacs.
So is Intel going to do a cheaper Itanium for  Apple or is Apple going to pretend that 64-bit never existed? Yes to  both is my guess.
 Why announce this chip swap a year before  it will even begin for customers?
This announcement has to cost Apple billions in lost sales as customers inevitably decide to wait for Intel boxes.

Then what is the driving  force?
 Microsoft. Intel hates Microsoft. For Intel to keep growing, people have to replace their PCs more often and Microsoft's bloatware strategy just isn't making that happen, especially if they  keep delaying Longhorn. 
 This isn't a story about Intel gaining another three percent market share at the expense of IBM; it is about Intel taking back control of the desktop from Microsoft. So Intel buys Apple and works with their OEMs to get products out in the market.
 That's the story unfolding. Steve Jobs  finally beats Bill Gates. 
 And with the sale of Apple to Intel, Steve  accepts the position of CEO of the Pixar/Disney/Sony Media  Company.’
