Innovation? Hardly. Innovation should not be confused with new projects. Imagine a car with a broken radio and a weird steering problem that causes it to veer to the left too often. At Microsoft the culture and incentives would drive them to put a panel over the old radio and install a brand new radio along side it that did most, but not all, of what the old radio did. Then they'd add rockets sticking out from the left front fender which turned on periodically to correct for the drift. It may seem like this exaggerates the situation a bit but it really doesn't, it's just that bad.
