John Gruber responding to criticism about how Microsoft wasted time publishing concept videos:

Putting this “Future Visions” video in public squanders attention that Microsoft could otherwise have focused on its current and imminent new products — like Windows Phone. Take a new iPhone 4S and a Windows Phone 7.5 device back in time 20 years and they might seem equally impressive to a pair of 1991 eyes. But one of them sold more in a weekend than the other does in an entire financial quarter.

It’s hard to argue with that.
