A year ago I went on a road trip with my Daughter. She comes on the forefront of generation Y. I hadn't seen her for a while and was annoyed that the iPhone was "demading" her time. By the end of the trip my attitude had adjusted. My "navigator" found the cheapest gas, where the pizza was, the weather, etc...
And the dohicky has an altimeter, and lat/long plotter.
I adjusted.
