Yes, twice the screen, but also double the thickness, at least for the LCD and some supporting components. Figure on at least a few mm extra (LCD+touchscreen+case). I don't know of any material which can fold 180 degrees over and over, and not eventually succumb to fatigue. Maybe within the expected lifetime of a phone it will work under test conditions, but unless there is serious margin in the robustness, I would expect some to die at the fold in the real world, and that will never be good publicity.
