I see your point, but the phone example actually plays into the post-pc argument. And when it comes to spreadsheets, I'd argue that there are tons of people that don't do much with this. Sure, apple or whatever post-pc company might appear might not take over the corporate world, but it might still be a scary thought to microsoft that the post-pc devices, tailored to needs (iPad: simpler creation and consumption, iPhone: on the road calls and other stuff) could take a significant chunk of their revenue. Betting on just corporate, and not the creative sector at that, might be putting too many eggs in one basket. So I agree that the post-pc device can never take over certain functions, but it can replace enough to make microsoft worry.
