A few weeks after Lenovo announced four 8- and 10-inch Android and Windows Yoga 2 tablets, the company has refreshed the lineup with a new 13.3-inch device running Windows 8.1.

The new tablet sports Intel’s 1.86GHz Atom “Bay Trail” Z3745 quad-core processor, a 2,560x1,440-pixel display, 4GB of RAM, and 64GB storage -- expandable up to 128GB using a microSD card slot. Connectivity options include Bluetooth 4.0 and 802.11n Wi-Fi, and there's also a 1.6-megapixel camera up front.

In addition, the device contains Micro-HDMI and Micro-USB ports, packs a pair of speakers on either side, with a 5W JBL subwoofer on the back, and comes with a detachable keyboard that also doubles as a cover and connects to it via Bluetooth. It weighs in at 2.27 pounds (without keyboard), and claims 15 hours of battery life, thanks to a 12,800mAh battery.

The tablet can be used in four modes: hold, stand, tilt, as well as a brand new hang mode. There's no built-in pico projector as it wasw the case with the $499 Lenovo Yoga Tablet 2 Pro, which was also announced earlier this month.

Lenovo says the 13-inch Yoga 2 Tablet will hit shelves in the US next month, and will retail for $699 (keyboard included). The company didn't announce pricing and availability details for other regions.
