[CEATEC 2009] Sony is showing a few cool OLED prototypes: a reader, a bracelet and a laptop. The most eye-catching one is the all-display laptop that ditches the physical keyoard in favor of a virtual one. It looks amazingly light, but you can bet that no one was allowed to touch the concept displayed behind thick plexiglass. The display is flexible and Sony was demonstrating other panels playing video while being flexed. So… hot or not?
