Never mind the fact if you get n a wreck and destroy the phone, gonna make it hard to call for help.
DaMoron has a Droid phone of some kind. Didn't seem to have any problem with discharging. My Casio is mil-spec. Waterproof, dustproof, etc. I've tested its abilities a coupla times.
Smartphones aren't the final answer for sure, but a move in a good direction. I haven't even installed the gps on PandaBike. If I need directions, or to find fuel, food, etc, I just pull out the phone and go to Google Maps. The gps is living in the car so my wife can get further confused.
