I know that the M9 is going to be a "must have". I also know that you will be able to view your location and plot out your trip with the uplink capabilities, and keep track of weather and your location; keep a diary in-fact. Specifically with tide information I have not been able to use one of these, so I only know what I have been told. The M9 will be out shortly, (due out in December or early 03') we will no much more then... But what I have seen, this wrist-top computer is just that...not a watch!
