I was close-minded once. (Well, OK, more than once)
When cell phones first came out, I got down on some woman for hers ringing at a shelter.
Sorry.
Now, I'll say this: if you were going to carry a camera, maps, compass, flashlight, radio, GPS, anyway, why not use an "all in one" tool.
And imagine: you can even use it for a phone sometimes.
The problem of course is charging.
And that takes extra weight items that can be heavy.
So yes, it can be a toss-up.
But for me, I can also work and keep in touch with my family so it's a no brainer.
