From the current issue of Wired in an article by Mat Honan - - The Simple Complex: Why subtraction is the hardest math in product design:
"Simplicity is about subtraction," says Mike Monteiro, author of Design Is a Job. "We live in a culture of consumption, where quality is associated with more. So designers and manufacturers tend to believe that to succeed you have you have to provide more. What if Microsoft announced that the next version of Office had 75 percent less functionality? It would be usable? But there's no way marketing would led them get away with that."
