Useful tip: for carrying a pocket digital camera, keep it in a $5 microfiber bag like the ones used for sunglasses (easily obtainable at a sunglass store if you don’t already have one).
It adds nothing to the size, so the pocket camera still fits in your pocket. It protects the screen, and keeps the camera reasonably free of dust. It doesn’t protect it against drops, so don’t drop your camera — sure, you could get a padded case but then it’s no longer a pocket camera.
I’ve kept my last 3 pocket-sized cameras in nothing more protective, while they lived years in my pocket accompanying me on various adventures, and they’re all faring fine, except for one which I landed on in a skiing crash. Oh well.
