I seem to remember Microsoft paying half a billion dollars for Danger and then spending years rewriting everything on Danger's platform from Java into their own in-house technologies. (with the usual infighting about what division would own the rewrite and which in-house technology it would be based on) By the time they were done, the iPhone had launched and it was just too late.
