Lenovo had a surprise in store after it confirmed the IdeaTab S2 by giving a preview of its K2 cousin: the second model will run on a quad-core Tegra 3 processor and carry the same 1080p screen concept as the Iconia Tab A700. Both, however, are part of a Lenovo strategy to make up for the rough start from the K1. We tried both ahead of CES and got to see if it will be much of a threat to the iPad.
