"I don't own a cell phone, but I'm not shocked that people do. I don't know what the typical cost of a cell phone is, but I imagine that a few years of coverage would cover most of my gear (and I get to keep my gear)."
A lot, at least if you own an iPhone. I've got about the cheapest iPhone plan, and that's a bit over $85 a month.
But I love my iPhone, and it's part of my backpacking gear! Why! Because, since it replaces so many other things, it's actually UL! :-)
I use TomTom on my iPhone to get me to and from the trailhead, I have a couple of field manuals on there that can assist in an emergency situation, a first aid program that shows me how to handle different first aid situations. I've got a program on there that shows me different knots and how to tie them (since I'm still learning knots), I've got a program on there that orients to the sky so I can lean back and gaze at the stars and know what I'm gazing at. The camera has shown itself quite good enough for trail shots (for me, anyway). Games if I want to idle away time waiting for others to catch up to me. Trail maps. Rudimentary GPS. And much more. I love it!
