The problem of Xerox was that they research group produced things much beyond their ability to market and execute. Xerox executives thought about the world in terms of printers, not in terms of revolutionary computers. They could have made trillions of dollars if they had executives who truly understood and valued innovation.
They only barely understood the world in terms of printers, too. If they'd capitalized on their entire portfolio they could have taken over the world and we'd probably be a decade beyond where we are now.
