One doubts Samsung’s convictions at their own peril. The company will be the first to point to the O.G. Note phablet as the ultimate expression of this phenomenon. The line may be gone, having been absorbed into the flagship Galaxy S product, but its influence on the industry is still being felt a decade after its release left pundits wondering whether the company had utterly lost it.

A convincing argument could be made that the Note, too, gave birth to Samsung’s foldable ambitions, as well. While it’s true the company has done an increasingly good job shrinking the screen-to-body ratio, there’s a very practical limitation in smartphone screen size. At a certain point, one simply runs out of pocket, and 6.8 inches might just be that figure.
