Siri might be a breakthrough app for iPhone. You ask the app a question and it hits a database and sends you back what it thinks you are looking for. It uses Dragon's engine for speech recognition (which is good) or you can just type the question in manually. We're not exactly sure what's going on behind the scenes, but it sounds a lot like Hunch. - where it gets smarter based on the community and increased personal knowledge.
