Great if you're lost in the desert, not so much if you are spelunking.
At the $25 a month level it might be worth it for my wife or I to switch out one of our phones for one. The only reason we need two phones is in case we get split up and the unlimited text feature would mitigate that. On top of the safety factor, it would also be nice for our friends and family to be able to keep track of where we are, for piece of mind and general stalkeriness.
The $300 buy-in plus $300 a year is still more than the $480 a year we'd save on the 2nd phone though, so it's a tossup. We do plan on doing a lot of hiking and we're not in the best of shape, so there are risks, but we're also not doing anything really dangerous like climbing or camping in the backcountry (though my wife might claim otherwise - she had her eyes closed most of the time driving the bear tooth highway).
