The new iPhone and Keynesian economics

In The iPhone Stimulus Paul Krugman uses talk of an iPhone led recovery to explain Keynesian economics
What I’m interested in, instead, are suggestions that the unveiling of the iPhone 5 might provide a significant boost to the U.S. economy, adding measurably to economic growth over the next quarter or two.

Do you find this plausible? If so, I have news for you: you are, whether you know it or not, a Keynesian — and you have implicitly accepted the case that the government should spend more, not less, in a depressed economy.

The core of his argument is this:
And to believe that more spending will provide an economic boost, you have to believe — as you should — that demand, not supply, is what’s holding the economy back. We don’t have high unemployment because Americans don’t want to work, and we don’t have high unemployment because workers lack the right skills. Instead, willing and able workers can’t find jobs because employers can’t sell enough to justify hiring them. And the solution is to find some way to increase overall spending so that the nation can get back to work.

He also gets it right with this:
Yet far from using public spending to support the economy in its time of trouble, our political system — driven by a combination of ideology, exaggerated deficit fears and Republican obstructionism — has moved to make the depression worse. Yes, unemployment benefits and food stamps are up, because so many more people are in need; but government employment has plunged, as has public investment.
