The extensible display can effectively double its size through the use of a crown that also activates the rotating mechanism, plus the touchscreen supports S Pen inputs. There is an under-display camera and a suite of sensors, as well, so this type of device could soon replace a smartphone.

wow! this would be interesting.
not since the Gear S would Samsung have a smartwatch with a screen that large. it'd rather they focus on a larger, curved screen with a thinner body instead. but I can see the tech-appeal to the general consumer.
...get the rolling watch with a new foldable. (?) Galaxy Watch R or Roll (?)
