I've said this for years, since I owned a Samsung Galaxy something with the dock that had USB, ethernet and HDMI; you put your phone in and you have a desktop...

This will be the future, but only when Apple does this to their iPhones lineup; the experience will be consistent and seamless; I'm not a fan boy, but one thing i'm sure is that they will release this and it will be like working on macOS, but you have it in your pocket.
