Yeah, this could be a VERY interesting device if the rumor is accurate about the display. The only big question I have is what is done about scratch resistance once you go down this flexible display route. The paper thin Mylarish nature of the display though could mean near bezeless designs I am guessing as the display could basically be taped to the face of the device if I understand what is going on here.
Introducing such a design on a Note variety product would make sense.
Now just for the concept/design geeks reading think of pairing this sorta display with a planar speaker set just below it. There could be three speakers that are just different zones of the display. A top for handset use and two below for stereo speakerphone/music. All with a near zero bezel display on top of them.
