How bout using your Droid gps to find a friends new home. It guides me there flawlessly and says you've arrived at your location - then chimes - what's that I think to myself picking up the Droid - "Good golly Miss Molly" it's got a picture of the house on my phone and its the correct picture.
And, you know what's coming next?!?! They will probably have an app to assess the character of the person your visiting. The phone will query - Are you sure you want to visit the homeowner? He/she is a level II safety risk and has a level I moral status rating - profile includes speeding tickets, failure to maintain lawn, 2 affairs - both genders, now divorced, morbidly obese and a mediocre credit score!
Ding - Do you wish to proceed?
