Title: Excellent device
Review: I'm very happy with the device. I really appreciate the integrated electronic compass. The integrated altimeter seems to need a lot of calibrating, though. The altitude reading from GPS seems to be more accurate most of the time. Battery life is not great, especially when satellite signals are weak or you use the backlight a lot. However, it's everything I want with lots of interesting features I didn't expect.
