Man, am I glad my mother didn't have one of these to pin me down when I was a kid. I loved my freedom, and she would have loved to track me down. No one seems to like the idea of big brother watching our every move, even if we're doing nothing wrong, yet we seem quite happy being big brother, and we use the same reasoning they do to justify it... vvoelema.
Excellent comment in response to the Filip, a device that can be used to track your children, but as a parent I still like the idea of being able to know where my kids are. As a parent, I should also have their best interests at heart. Unlike the authorities so there are two types of big brother I guess.
