We've already seen Sony take a stab at a Windows 8 hybrid in the form of the VAIO Duo 11, and now a clip has appeared on YouTube apparently showing an unannounced 13-inch Ultrabook slider with a 1080p Triluminos touchscreen display. Allegedly, the video is being used for training at UK retail chain Dixons, and in addition to repeatedly collapsing and opening the slim white and silver unit, the demonstrator plays around with a stylus in Microsoft's Fresh Paint. There are a couple of text overlays near the end of clip, highlighting the "SurfSlider design," backlit keyboard, ClearAudio+ and ActiveSleep tech, as well as its 10 hours of battery life. NFC is also said to be on board, along with an 8-megapixel camera with Exmor RS sensor, Intel Core i5 processor, 4GB RAM and 128GB SSD. The incredibly grainy video is embedded after the break, and although we can't verify its authenticity, we also can't ally it to any known product.
