I do. That quote doesn't just say that PC demand stagnates, it says it goes down, massively. It says that from X people who, at the time of that speech, use PC's, only 1 in the future use PC's. And we're seeing that's not true even if X=2. And X was never supposed to be as low as 2. What we are seeing is that a massive amount of computer USE moved over to phones and tablets -- tons of web browsing, tons of email browsing, calendaring, etc. Probably if you looked at the PC era and the post-PC era in terms of seconds in front of a screen or whatever instead of people, you'd see that 1/X ratio. But for people, it remains useful for almost everyone to have a PC -- even if they use that PC less than they used to.
