More than six months after making its debut at CES, Lenovo's IdeaTab S2110 has now gone on sale for $343. Originally announced as the S2, the S2110 comes with an optional keyboard dock reminiscent of the Transformer Prime, and features a 10.1-inch, 1280 x 800 IPS display. Powered by a 1.5GHz dual-core Snapdragon S4 processor, the tablet also runs Android 4.0 Ice Cream Sandwich, and includes a 5-megapixel rear-facing camera coupled with a 1.3-megapixel sensor up front. The 16GB and 32GB versions are available for $343 and $375, respectively, though the optional keyboard — replete with dual USB ports, SD slot, and ten extra hours of battery life — will cost an additional $56.
