There was a huge battle between GM and Microsoft at COMDEX years ago, when Bill Gates said, "If GM had kept up with technology like the computer industry has, we would all be driving $25 cars that got 1,000 miles to the gallon." GM got pissed and issued a press release suggesting how poorly a Microsoft-built car would operate, comparing it to Windows -- how often the car would crash, how incompatible it would be, and so forth.
