Lenovo has announced a new line of touch-based devices running Windows 8. The company revealed new additions to its IdeaPad U series of Ultrabooks and the Mainstream Z Series, along with the new ThinkPad Edge E431 and E531 business laptops.

"People love touch. It's everywhere in today's PC Plus world and is driving new interactions with devices and digital content," said Peter Hortensius, president, Product Group, and senior vice president, Lenovo.

Hortensius further added "We've aggressively integrated touch across our consumer PCs so that we have one of the largest portfolios of Windows 8 touch products available."
