The problem with dedicated cameras is that they have a very dated interface that is not for modern times, and that for simply sharing an impression the quality of the smartphones is already overshooting. So dedicated cameras are now only for people seeking to snap great photos, and willing to put up with a lot of annoyances to finally share those photos.
To share, the connection must be wireless, and once set up, pictures must appear magically on the smartphone: you want the experience to be: shoot on the camera, quick check on camera, pick up phone to share the photo. Allow for automatic posting to be configured on the phone. Spending 30 seconds to move a file via memory card is simply too much, not to mention not even possible with most phones.
The issue is of course that it is impossible to achieve this kind of integration without help from the smartphones, that they must provide a way to implement background transfers. The technology is there, but it must be supported by Google and Apple. Apple actually has implemented everything to make AirDrop a reality, it would need to provide a way to extend it to third parties. Of course the camera makers have lost the influence to get these connections made.
The user interface of the cameras is also pretty problematic, especially since they have now so many options to configure instead of allowing us to concentrate on the artistic process of creating impressive photos. As an intermediate step one should move everything not typically changed during shooting to the much better interface on the phone.
