I would love something like this if it used a real hinge or a slide instead of a folding screen. Best of all IMO would be a three part screen (two hinges/slides) with a 1:2:1 ratio so that the line - which can be small with modern bezel-less design but still present - won't be in the middle. That makes it usable for games etc. as well as many tiled terminal/editor windows. Innovation is great and all, kudos to them for trying this, but validating the UX aspects separately from the base display technology seems worthwhile.
