Take a look at the FlexPai folding phone product page. This is the first folding phone concept I’ve seen that made me see a path to the future.

If you scroll about 3/4 of the way down the page, you’ll see the phone folded in half (sort of), showing three displays, with an interior and exterior display as well as one for the spine.

The design feels clunky to me, the folded phone too bulky for my pocket, but I can absolutely see the value of a phone thin enough to fit in my pocket that unfolds into a full size tablet. Best of both worlds.

I can’t help but imagine such a device from Apple. Someday.
