I'd contend that the greatest advantage you mentioned are the least technical ones. It's the manual controls and handling. At some point, especially with the help of computational photography, smartphones will close the gap entirely, but if I'm shooting an event, there's no way I'd even try doing so on a phone. I just won't be fast enough. On a phone, I'm never going to be able to spin around and shoot at some fast action I saw out of the corner of my eye and expect to come away with a good photo.
