The fact that users can track people and watch their every move is kind of scary! Yet it could come in hand in some points in life. Lets say your child is going out with some friends. Well you could open Google maps on your computer or you iPhone and see where their really going. In a bad situation, a stalker could start fallowing you simply by the common knowledge of his Blackberry cellphone. All in all, this is a very troubling feature! Once the update becomes available on my iPod Touch and my Motorola Hint, I will definatly try it out!
