The Huffington Post is onto something.In a recent report, the website listed seven things that the iPhone, first released to the public only seven years ago, has made obsolete - though there are surely plenty more than seven.Up first, says the website: roadmaps. Thanks to Google Maps, which anyone can use on his or her cellphone, nobody uses paper maps anymore.I can’t begin to imagine how much stress this is saving vacationing families.Pre-Google-Maps horror stories were legend when I was a kid in the ‘70s: Neighbors who thought they were heading east to the beach unwittingly headed west and had no idea of their error until they hit Indianapolis.I remember being lost for hours in our station wagon, several maps sprawled across the dashboard and front seat, my father grumbling to my mother, “I knew we should have hung a Louie at Breezewood!”Yeah, good riddance to paper maps.That brings us to another item made obsolete by iPhone innovation: the alarm clock. Every cell phone has an alarm app now.
