Lenovo also announced the IdeaTab Lynx tablet, with an 11.6-inch screen, Windows 8 and a dual-core Intel Atom processor code-named Clover Trail. The tablet weighs 640 grams and offers 16 hours of battery life with an optional dock. The device will become available starting at $599, with the optional dock priced at $149.

The company also announced the ThinkPad Twist, which the company said is a "twist" on traditional ThinkPad design. This ultrabook, which is designed for small businesses, turns into a tablet after the screen is turned around and placed over the keyboard. The convertible laptop weighs 1.58 kilograms and comes with a 12.5-inch screen, similar to the popular ThinkPad X220. The laptop will come with Windows 8 Pro and an Intel Core processor code-named Ivy Bridge, and it will become available on Oct. 26 starting at $849.

Lenovo also announced that the ThinkPad Tablet 2 will start at $649. That 10.1-inch pure tablet comes with Windows 8 and Intel's low-power Atom processor. It will deliver between eight and 10 hours of battery life, and a detachable keyboard will be sold separately. The Tablet 2 will go on sale on Oct. 26.
