Lenovo IdeaTab S2110
The Lenovo IdeaPad S2110 was first seen at CES 2012. It is much like an ASUS Transformer, with an optional keyboard dock one can purchase separately. With a Snapdragon S4 processor, 1 GB of RAM and full SD card compatibility, this bad boy does happen to be a great option. And of course, that $399 price-tag won't hurt either.
