Waze: Waze, the free, light-hearted turn by turn navigation app, just got its upgrade to 2.0, and it's a more viable replacement for the Navigons and Telenavs of the world than ever. In addition to being generally snappier and shinier, Waze 2.0 adds a neat group feature for organizing carpools and a system of rankings and achievements, you know, for making your commute fun. Wonderfully free.
