I do not see anything missing except for RAW and exchangable lenses
A nice large sensor, that's what's missing. (Using a 'smart'phone camera) It's like looking at the world through a pinhole.
I long for the day we can have a 10" X 8" sensor, a nice big lens, a lovely heavy tripod and a back cloth to compose the image under ...and movements of course!
Just my idea of a dream camera, spend half a day composing and taking one photograph. (Rather than having the camera rattle off fifty and it select 'the best'.)
Point and shoot is what you do with a gun.
