has been updated to give you what you need and when you need it. It gives you the weather of the place you are visiting so you have time to pack the clothes for that weather. Your boarding pass is pulled up when you arrive at the airport (it only works for United Airlines, however). It helps you figure out what to do at the destination, by showing what's going on and popular places.
The voice search has also gained new features. You can ask what song is playing and it will listen and figure it out. You can also say "scan barcode" and post to Google+.
