Lenovo isn't done making exotic concept devices... far from it. The PC maker has unveiled a laptop concept whose centerpiece is a flexible screen that runs right up to the keyboard. It's not joined by a hinge, it is the hinge -- you'd fold it up like a yoga mat, or maybe Microsoft's Surface Book. It wouldn't have a trackpad, but you could write on it and speak to it. There's no guarantees that Lenovo will build it (the company tells us that there's no hands-on time "yet"), but we wouldn't rule it out at some point in the future, either.
