Asus's Transformer tablets are getting some competition at CES, folks: Lenovo has just unveiled its own 10-inch tablet with a detachable keyboard dock for extra battery life, and on its own, it's just a third of an inch thick and weighs 1.1 pounds. Unfortunately, the new IdeaTab S2 isn't a quad-core rig like the Transformer Prime, but it will have Android 4.0 out of the box, running on Qualcomm's latest dual-core Snapdragon S4 MSM8960 processor. Lenovo says that it'll run its Mondrian UI layer and that, paired with the keyboard dock, the combination has up to 20 hours of runtime. We don't have a lot of other details yet, but we're hoping to get hands-on time soon!

By the way, Lenovo also took this CES opportunity to remind us about its LePhone S2, a mid-range Android 2.3 smartphone, which will now include "a unique Kernel-level security system" to make it appealing to the workforce, not to mention an "8MP super camera."
