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. Not that we're ashamed of anything we've done or anywhere we've been, but Garmin spokeswoman Jessica Myers has implied that the company knows how to retrieve that data from your GPS unit and is willing to give it up to authorities, but only does that on, as she put it, a "case-by-case basis." 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]
