Sony's Vaio Duo 11 has, as the name hints, an 11.6-inch screen.
That puts it on the large side for a tablet, and the small side for an ultrabook. In a professional context, though, both could have their advantages.
At 1.3kg, it is in line with ultrabook portability. The large touchscreen, which can be written on, could also be handy.
