I think the best point he makes is at the end: Ballmer is not a product strategist. He is in fact a fantastic salesperson, he closed amazing deals for Microsoft when I worked there. But he has no business defining product strategy, creating or killing product lines or trying to imagine what the public will want or what's attractive to customers. That stuff should all be left to Bill Buxton.
