There is one more use case not covered by smartphones but actually covered by fixed-lens cameras - taking photos in rainy weather (which in some parts of the world is hard to avoid) or underwater. While there are waterproof smartphones, capacitive touchscreen becomes unusable as soon as it catches even a few drops of rain or water from wet fingers. A camera like Fujifilm XP140 works well in rain as long as there are…
The iPhone is waterproof and you can take a photo with the physical volume up/down key. I've used it underwater a couple of times, none of my other proper cameras would be able to do that. My two cents.
Asking for a me who doesn't want to fuck up a thousand euro phone trying something stupid next time I'm at the seaside :)
