In a chat with fellow CEOs at Microsoft's 14th annual CEO Summit, Microsoft boss Steve Ballmer came close to admitting Vista was a dog."How do you get your product right? How do you help the customer? How do you be patient?" he asked, as if he knew the answer. What he did know was that Microsoft spent too many years building Windows Vista. "We tried too big a task and in the process wound up losing thousands of man hours of innovation," he said.
