For iPhone users who could use some help with organizing your day to day grind, but don’t have room in the budget for a persona assistant–take a look at Siri. It is a handy voice-recognition tool and free download from the iPhone apps store.

The video gives a pretty good idea of how well Siri squeezes several uses into the interface. You can get directions, look up event times and set up schedule notifications.

The demo even shows a pretty impressive display of the user giving the app confusing directions, but Siri’s smart voice recognition manages to interpret — and pull up local cab listings. Definitely worth a look.
