His book The Design of Everyday Things is a classic, and taught me how to shop for a refrigerator. (Seriously.) However, his recent rant about Google is just plain wrong. His basic point—that it’s easy to make a simple interface to a system that only does one thing—seems sensible enough. But is it true?
