Apple Watch 4 looks prehistoric compared to this crazy new smartwatch

In the past couple of weeks, we have seen smartphones with foldable screens of various form factors. This will be the evolution of smartphone technology and the old candy bar form factor will be passé giving rise to single-fold displays, multiple folds and more. Samsung CEO DJ Koh suggested that smartphones with foldable screens were the next step but later on, wearables will be the in thing when it comes to smartphones. These words appear to be ringing true a lot sooner than expected and while Koh claimed that in five years, wearables would take over, several brands are started to patent devices that can be worn on the wrist which open up to a smartphone or even a tablet.
