I just discovered a free GPS app for my iPhone called Waze. Free is usually an indicator of a light version of a full app. Not here. I have played around with and paid for some full featured navigation apps and have not been terribly impressed. I actually just drove from NYC with my brother, to Greensboro NC. We had two iPad, two iPhones and a built in GPS in my brothers vehicle. It was a Mo, Larry, Curly moment. We stopped multiple times by the side of the road to determine why all the devices were giving us different info, and actually got lost once. I am just glad my wife wasn't in the car or I would still be hearing about it. Anyway, I digress.
