Lenovo has just finished unveiling its latest Yoga tablet, an Android-based slate with up to 18 hours of battery life. Ironically, Lenovo has Ashton Kutcher on its side, remember that Kutcher played Steve Jobs in the movie 'Jobs'.
The Yoga's screen can fold over at 135 degrees, which allows for three different modes of use. You can use the Yoga in the traditional tablet mode iwth the kickstand closed which is called "Read mode" or you can open that kickstand up so that the tablet is held up on its own which is known as "Stand mode".
The final "Tilt mode" allows the Yoga to lay down, but with the battery at the back keeping it propped up ever-so-slightly, enough so that it is much more readable and easier for typing when slanted that way.
