I have owned the GC for a year, now the joystick is almost broken (rubber peeled off, won't "click" anymore). I am not satisfied. I'm actually looking to buy and etrex 10 because it is more reliable and much simpler (the GC's interface is slow and glitchy, and the gps takes too long to connect). In my opinion, don't go with the GC, it may be cool but it is not a very rugged and reliable device.
