There is new technology available for GPS which supposedly makes it accurate within an inch which sounds like overkill when you are driving from Boston to Buffalo. I mean how many times do you need to know, to an inch of accuracy, which part of the MassPike you are on??!
But then I came up with something where this might have some real value, trying to find a lost phone or set of keys. If I could use a GPS locator to tell me that my phone is not just in my house but in the third drawer next to my hello kitty socks, that would be a service that I could see being incredibly helpful. Time to put a GPS tracker on everything I own...including my kids
