Lenovo IdeaTab A2109
This device is released during a very hard time to compete. It is set to compete against other 10-inch tablets like the Samsung Galaxy Note 10.1, the ASUS Transformer Pad Infinity and the Acer IconiaTab A700. This one is a bit on the lower-end when it comes to its price, though. $300 gets you a 1.2 GHz Tegra 3 quad-core processor, 1 GB of RAM and Android 4.0.
Not too shabby for a 10-incher with those specs!
