I know Apple is sitting on a lot of cash. A lot.
I think it would be fascinating to see Apple purchase Bing and rebrand it. With search built into the iPhone and the future value of mobile search in mind, I think it would be near foolish for Apple to miss this opportunity. Otherwise, no matter how well the iPhone does, Google will still always have its hand in mobile advertising money.
But what do I know?
I think it would place Apple and Google in a very interesting competitive position.
