Notebook makers seem to be settling on two designs when it comes to Windows 8 hybrids: A fold-over, like the Lenovo Yoga 2, and a detachable, like the ASUS Transformer Duet. Thats just what Toshiba has done with its concept hybrid notebook, whose keyboard not only folds completely behind the display, but also detaches for the times when all you want is a tablet. Unlike most detachables, though, Toshibas device doesnt divide evenly in half.
