""Too large to function good as a watch and too few features to be a good GPS". In a way, that is true, but it is really small and works quite fine. It can get a gps-fix in about four seconds, which is quite fast compared to other units. Because of it's size, it has a small antenna, so you can forget about gps indoors or dense tree cover. Another drawback is that it displays the coordinates with degrees, minutes and seconds. This gives ~30m insecurity in one direction and ~15m in the other. This could be better, now when SA is gone. It is expensive too. It costs about $500 ($800 in Sweden).
Why should one get it? - It's cool, small, fast and a Casio (which means you can hit it with a hammer and it will probably still work).
Besides, you can have a good excuse to have a gps-unit with you all the time - it's a watch!"
