One of the world's biggest laptop vendors, China's Lenovo offers a wealth of different Windows 10 devices in its current portfolio from the Yoga tablets and convertibles to the Thinkpad line of more professionally targeted Ultrabooks.

As of CES 2015, Lenovo's range topper is the Thinkpad X1 Carbon. Built in part to celebrate 100 million Thinkpad products sold worldwide, the X1 Carbon packs the latest hardware from Intel into a sleek, yet tough package with a stunning display.

Also of note is the Anypen technology developed by Lenovo and embedded into its 8-inch Yoga tablet. As the name implies you can use any pen, pencil, even a carrot or a pair of scissors to write on the display.

At IFA 2015 Lenovo continued to pad out its range of Windows products, announcing several at once. The most notable are the MIIX 700, the company's take on the Microsoft Surface, the new Thinkpad Yoga complete with integrated pen and the spinning off of its gaming brand, the Y Series.

The Y Series covers the whole ecosystem of gaming products. Lenovo's got laptops, desktop rigs with tool-free access for swapping out parts, mechanical keyboards, mice and even headsets. It's one of the big growth markets in Windows PCs at this time so expect to see much more in the future.
