Sony VAIO Duo 11

Following on the theme of IFA hybrids, Sony pulled the covers off the VAIO Duo 11 - an Ultrabook with tablet functionality. A sliding design allows you to use it in with the keyboard or slide it into tablet mode, in a similar way to last year's the Asus Eee Pad Slider. Running Windows 8, it features an 11.6-inch full HD screen, packs a fully featured Intel Core processer, optional stylus for more intricate tasks and weighs in at a reasonable 1.3kg - not bad considering there's a built-in keyboard.
