I love my droid phone (verison) i've used the gps to follow tracks in deep brush in the middle of no where. Worked great and could zoom in to within yards of where i was. Only problem is you can't really use it like a normal gps, the screen turns dark in a min or two and there is no voice commands. Turn by turn are okay, but dont update themselves. I use it to find things when i'm in the car or have the wife with me in the car, or i have navigated with it on the dirtbike when i stop, but you half to stop, no real way to mount it and use it.
