"the app also includes smart tidbits from a range of data it pulls from the web. In one example, Cluzee adds to reach the doctors office on time, you should avoid Main Street because of construction following the mention of a doctors appointment, using traffic data to ensure the user reaches his appointment on time"
This type of integration of personal data and relevant public data is the future of Siri-type services. I'm waiting impatiently for Siri integration with third-party apps. For example, given I have the myTrains app, and the phone knows where I am, I ought to be able to ask "When is the next train to Leeds?" and have Siri give me the answer.
The fact that Siri has competition is excellent news, as it will push both platforms into progressing further and faster.
