Sony has jumped on this concept at IFA 2012 with the Sony Vaio Duo 11. The device is both an Ultrabook and a tablet – a 'handy' tablet as Sony explains in its press blurb.
Although this sounds like a concept that's going to add extra chunk in the hand, it really isn't.
Although when you lift the Sony Vaio Duo 11 it definitely has weight (1.3kg of it, which is a little heavier than the Microsoft Surface), it is a mere 17.85mm thin when flush and in its tablet state.
The tablet-laptop comes with a 11.6-inch full HD touchscreen panel (1920 x 1080), which you can prod away with using your own fingers, but there's also a stylus on board.
What with Samsung and its S-Pen functionality and Sony with its Duo pointer, the stylus is definitely back in fashion
