The more I read about Duarte, the more I realize he must have had a very strong support team at Palm/HP, because so much of what hes done and said after moving to Google has been complete drivel.
Theres a seminal study of voice recognition, I cant recall the lab or year off the top of my head, but the outcome of the study was basically voice recognition accuracy was considerably higher when the computer behaved more like a human. They studied phone conversations and found, absent body language, humans have a series of verbal cues and responses to let the person on the other end of the phone know they are still listening. Its something Siri does quite well, and I assume will only get better.
Google will have a tough time matching that concept, they simply dont have the corporate culture that fosters delightful experiences.
