Lenovo  unveiled its IdeaPad Yoga recently at CES, showing off a notebook with a 360 degree hinge designed to be used in a variety of ways in addition to the conventional laptop style.

The Ultrabook, which will run on Windows 8, can be opened and folded back on itself to be used as a tablet or e-reader with touchscreen capabilities. It can also be propped up like a tent for a better video watching experience, for example, or used as a traditional laptop.

Convertible tablets aren't a new idea, but on the Yoga, the hinges are designed to be sturdier than the swivels used in the past. When it's flipped and used as a tablet, the keyboard deactivates, so it can be placed on a flat surface or used on the go without worrying about hitting a key. The palm rest has a leathery surface so it can rest firmly and easily while being used as a tablet, and the whole device has a rubbery coating for durability.
