Lenovo is hoping Windows 8 users will want to flip, fold, twist, and turn their way through the new operating system when it launches at the end of the month.Announcing a bevy of new laptops-come-tablets in New York on Tuesday, the company is trying to make sure that if you are going to buy a new Windows 8 device when the OS launches on 26 October, you'll want to buy it from them.The Lenovo YogaLenovo has announced a new family of four convertible devices designed for Windows 8\/RT. For consumers, the touch-optimised family includes the IdeaPad Yoga 13, the Yoga 11, the IdeaTab Lynx - a dual core Intel Atom-based tablet; and the ThinkPad Twist, a "business-ready" device that supposedly puts a new spin on the traditional convertible tablet - it's basically Lenovo's take on the Asus Taichi.The IdeaPad Yoga 13 comes with a 13.3-inch high definition IPS touchscreen display on a hinge that allows it to move 360 degrees and fold from laptop to tablet in one simple motion. As one of the world\u2019s first multi-mode Ultrabooks, Yoga 13 comes with Intel's third generation Intel Core processors and of course runs Windows 8. It will measure 16.9mm thick and come with eight hours of battery life.The Lenovo YogaThe Yoga 13\u2019s smaller screen size counterpart, the Yoga 11, is the world\u2019s slimmest multi-mode PC, measuring just 15.6mm claims Lenovo. It comes with a 11.6-inch screen and a 13-hour battery life, \u00a0and you'll also get Nvidia Tegra 3 graphics making it the first, and supposedly only, quad-core processor Windows RT device at the moment.The IdeaTab LynxThe IdeaTab Lynx is one of the first Windows 8-based tablets with a dual-core Intel Atom processor and comes in a more traditional tablet shape. The 11.6-inch tablet doesn't come with a built-in keyboard, but will offer you 16 hours of battery life (with optional base), and Dolby Home Theatre sound, and for those who must have a keyboard for typing, there's an optional one that will cost you extra. For those who like to plug stuff in there is a full sized USB port which, when attached to the base, works like a desktop docking station for your office. \u00a0The ThinkPad TwistFinally there is the ThinkPad Twist that Lenovo hopes you will use as a "full-performance Ultrabook", and then, as with the Yoga, twist the top to switch to a convertible tablet.The 12.5-inch ThinkPad Twist comes with a third-generation Intel Core i7 processor, up to Windows 8 Pro, optional 3G, large storage up to 500GB, or 128GB SSD, and the ThinkPad keyboard - yep, nipple included. Other specs to shout at the boss when you are suggesting he buys you one are a high-definition 350nit IPS display and Dolby Home Theatre sound.In the US the IdeaPad Yoga 13 will cost $1,099 and be available at the end of October. The IdeaPad Yoga 11 will be available starting in December and costs $799. The IdeaTab Lynx and options keyboard will be available in December. It costs $599 for the tablet and is $149 for the options keyboard. \u00a0\u00a0The ThinkPad Twist will be available starting on 26 October and cost $849.
