TrackStick has come up with a range of handy devices that tract your, or someone elses, movements.
The portable devices range in price from about $180 are battery powered and can track up to a weeks movements.
The idea is that you keep the TrackStick in your vehicle (or your spouses pocket) and connect it to your computer to track it on Google Earth.
All three devices are apparently accurate within 2.5 meters, the more advanced versions track temperature and altitude too.
This is all a very nice idea but if I were to have all this functionality I’d really like it to takae care of it live for me and not have to download the information to my computer later. The use of Google Earth is a very nice touch though.
