Needs to do more than merely fold out though, it needs to become properly rigid. Look at how people use tablets - they hold them with one hand, usually vertically or at an obtuse angle, and expect the overall structure of the device to be self supporting. They don't treat them with kids gloves, gently lay them on a flat surface, etc. I think that's where the first gen foldables will struggle. What people really want is something that's a clam shell design, with the screen on the inside, that folds out flat & snaps into place to make a rigid, totally flat surface, then folds back effortlessly into a phone/phablet size, with the screen safely protected on the inside. That's probably a couple of generations away though.
