Why Siri Is Still the Future

When Apple unveiled the iPhone 4S last year, the new phone looked just like the previous one. It had a better camera and a faster chip, but it could do only one new thing: Siri. Siri, as everyone knows by now, is a software assistant that takes spoken orders. No training necessary: just hold down the "Home" button and speak casually. Siri lit the cultural world on fire. There were YouTube parodies, how-to guides and copycat apps for Android phones.
