Locally based Siri's a stupid-smart voice recognition app that turns your iPhone into a personal assistant: just tell it what you're looking for and where, e.g., "a romantic Italian restaurant near my office", and it'll pull up n' rank your options from various sources online. If you want a reservation, just specify a time, and Siri'll book you by interfacing with OpenTable, so all that's left to do is hit Buca di Beppo and watch the sparks fly.
