I'm beginning to think of a camera as a bit of EDC carry, like my SAK. Last year I splurged and got a low end "smartphone", which has a simple (no flash) camera. At the time, I thought it would be useless (camera, not phone).

Instead, I found several occasions when I wanted to document something good (e.g. geese on a local pond) or bad (some neighborhood vandalism) that I stumbled on by accident. I used the camera on the phone and got reasonable results.

Carrying a separate camera, even a pocket camera, has no attraction for me--but having a decent camera as a part of my phone (thus part of my EDC) does have value (but I'm not sure I would call it, strictly speaking, a "survival" item). The phone itself I do think of as a high priority survival EDC.

I love when things multi-task.
