Fast Company: Many people seem to have a hard time imagining the usefulness of Apple’s new watch. “Yes, but people didn’t realize they had to have an iPod, and they really didn’t realize they had to have the iPhone,” said Apple CEO Tim Cook. “And the iPad was totally panned. Critics asked, ‘Why do you need this?’ Honestly, I don’t think anything revolutionary that we have done was predicted to be a hit when released. It was only in retrospect that people could see its value. Maybe this will be received the same way.”
