I first saw thw flexy OLEd screens from Samsung several years ago at InfoComm. They are cool, but it really takes good design and a real value in everyday use to make something like that go. think of google Glass.... it worked, but socially we weren't ready to use it yet. I would wager this has similar problems until there is a clear benefit to having a folding phone. People are really used to the current phablet design.
