Lenovo announced IdeaPad YOGA, the industry’s first multi-mode notebook with a 360-degree flip-and-fold design. Combining the tablet’s ease-of-use with the ultrabook’s functionality, IdeaPad YOGA gives consumers four-in-one personal computing, with four separate usage modes in one PC.

IdeaPad YOGA’s patented dual-hinge design is engineered to enable content consumption and creation spanning four intuitive usage positions ... notebook, tablet, stand, and tent …in one computer, while offering higher durability and stability than conventional convertible form factors. The 13.3-inch touchscreen ultrabook measures 0.67” (16.9mm) thin at 3.1 lbs (1.47kg). Powered by the Intel Core Processor family with a Windows 8 operating system, YOGA supports eight hours of battery life with up to 8GB RAM and 256GB SSD.

The IdeaPad YOGA multimode notebook will be available in the second half of 2012 with an estimated starting retail price of $1,199. Check out the hands-on video of YOGA below to see how it changes from laptop to tablet.
