New, previously unseen prototypes include an Sony Ebook reader using a fixed OLED screen, as well as a Walkman-branded digital multimedia player that is built into a wristwatch-like form factor and new VAIO notebook.
The new OLED Sony ereader is totally different from what Sony has now but it is banking on the low power draw of the OLED screen so future users will not be using the monochrome screens of today.

Neither of this was operational either, suggesting Sony still has some time before it anticipates any of these translating to real-world products.
