Inside the GPS Revolution: 10 Applications That Make the Most of Location

You only have to very quickly skim through this brief article on things that GPS is letting you do with a cell phone to start coming up with your own ideas. When, for example, can we start taking attendance with GPS? Did you know that you could scan a barcode with your smart phone and it could not only tell you how much it costs, but other locations nearby (or online) where the same product is available, perhaps for less money? Did you know you could tell it that when you are in certain locations, its ringer should stay off? DId you know you can tell it to understand where you are in a place where you don't always feel secure and it can, then, when you "shake" it , it "take[s] a picture, turn on its speaker, and dial 911 (or another emergency number) . The app announces each of these steps out loud so a would-be assailant can hear what's happening and give up." This is really only the beginning of this kind of stuff.
