commodity pricing, I'm not even an apple fan boy and I can point to the argument that negates the commodity competition concept. sometimes yes but not always...
besides, Ford and Toyota have had technology trade agreements in place for a long time. (Ford hybrids eg.) not something that is likely anytime soon between MSFT and Goog. not to mention the fact that Toyota's research dept is big enough and good enough not to need input from Ford. (and Ford's is quite good). The first thing to go in companies that are spiraling down is R&D, which shows up as lack of innovation. No vision, No R&D, No innovation, borrowing technology and lots of lawsuits...earmarks of the golden age of Steve Balmer.
