Seems like everyone needs a cel phone wherever you go - grocery store, to a friends house, getting picked up after school. But "back in the days when I was a kid" cel phones were good for emergency use, when you couldn't get to a pay phone (or wait).
You might not want to answer one when you're camping, but you might need to use it (if you can get reception out of the canyon).
But what about when the battery runs out? The iSol is a solar charger for a bunch of phones, and it works on your iPod too.
