I'll further agree that you should use separate devices. No, I'm not a veteran geocacher, but I've been around the world literally. Uncle Sam took me into some of the most miserable and harsh conditions man has ever seen. I would recommend that you have too many gadgets, than not enough. Yes, we would love to have a Super Duper GPS/Digital Camera/Cell Phone all in one. Here's the real problem. Imagine an accidental drop of this "all in one" device, whether into water, over a cliff, or onto a hard rock. You could destroy this all in one device. If that were the case, you have lost your GPS to get you out of where you are at (if you venture way off of the trail), and your phone to call for help. With separate devices, you will be much safer. It would be better to have a broken cell phone and working GPS, or vice versa. Any given day, I would rather have a working GPS and no cell phone. Maybe that scenario will slow you down on purchasing equipment that you may wish you never owned.
