Never Get Lost with Google Maps for Mobile

Product Name: Google Maps for Mobile

Why it's great: We all love Google Maps, but the mobile version is even more useful. It's easy to download, and has lots of good features. It always knows where you are, it shows up to date traffic, and most of the other great features of standard Google Maps. It's especially useful when you're walking around a city you are unfamiliar with

How it makes you more efficient:
1) You don't ever have to print out directions before you leave the house - whether you're driving or walking, it will help you get where you need to go.
2) There's no need to carry anything extra with you - it loads effectively to almost any "smart" phone.
