A lot of us gizmo goons use GPS all the time now, but it may not have occurred to many of us that our mild-mannered and innocent GPS units are constantly gathering data, including rate of speed, location, and time of day.

That would probably involve a subpoena. Too bad there's no easy way to delete that data and cover your tracks, you tomcatting Romeos. [Press Democrat]
