Lenovo has introduced a new 14-inch version of its Yoga 3 laptop cum tablet combination device, with a previously announced 11-inch model hitting the shelves first.

It comes with a backlit screen yet is only 18.3mm in thickness when closed, ensuring that when folded backwards into a tablet design, it is still thin enough to be held comfortably. The 14-inch screen has also been built into the same chassis you'd find a 13-inch display normally, for extra size efficiency.

Inside, it can sport up to 5th generation Intel Core i7 processor, has a Full HD 1920 x 1080 resolution on the touchscreen, and can have up to 8GB of DDR3L RAM. A Next Generation Nvidia GeForce GPU can also be specified to run the graphics duties. And the hard drive can be either a 500GB hybrid SSHD or a 250GB SSD.

Stereo speakers with Waves Audio certification are included and the battery life is claimed at up to 6.5 hours on a single charge.

Connections include two USB 3.0 ports, one USB 2.0 port, a HDMI output and four-in-one card reader.

Measurements on the new 14-inch model are 334.9 x 229.5 x 18.3mm and it weighs 1.6kg with the SSD, 1.7kg with the hybrid drive.

Along with the 11-inch model, the Yoga 3 devices will be available in silver, black, white and orange colour schemes and will be in the shops from February (11-incher) and April (14-inch version). Prices are £549.99 and £649.99 respectively.
