Lenovo Yoga 13

Here's another aptly named device from Lenovo. This is the larger of the two Yoga models, sporting a 13.3-inch, 1600-by-900 multitouch display and weighing in at 3.4 pounds. It initially opens as a conventional clamshell laptop, but at the point where you feel like you've pushed far enough back to break it, keep going. The entire screen folds all the way back to become a tablet device. There are a few positions in between laptop and tablet that act as convenient stands and this things can literally do the downward dog position.
