How do you get two detachable/rotatable controllers with a sub-5" screen (assuming reasonable top/bottom bezels)?
I've been wondering that myself. Technically you could. Holding my One Plus One the whole thing is just at 6" x 3". It's more than enough room on the sides to have comfortably spaced thumbsticks and face buttons, but when detached they'd be rather small in the hand on their own.
That whole aspect of this rumor just baffles me. It seems like such a dumb feature.
