We already informed you that Lenovo showcased the IdeaTab A2109 tablet at IFA 2012 in Berlin and now they have another two models to show. I’m talking about the Lenovo IdeaTab S2110, that we already knew about and the A2107, a slightly more minimal version of the A2109. The S2110 tablet is a 10.1 inch slate with an IPS LCD 1280 x 800 pixel display and 420 nits of brightness.

This slate attaches to a keyboard dock, that will allow you to switch between notebook and tablet with ease. 10 finger touchscreen input is supported and inside the device we find the Qualcomm 8060A/8260A 1.5 GHz dual core processor aka the Snapdragon S4. This device offers 32 GB of eMMC internal memory and its battery will provide 10 hours of battery life. With the keyboard dock you will reach as high as 20 hours of battery life, but the package will be thicker. Without the dock the unit weighs 580 grams.

At the back of the S210 there’s a 5 megapixel camera with autofocus and single LED flash, while at the front there’s a 1.3 megapixel shooter for video calls. Other specs include 1 GB of RAM, Bluetooth 4.0, FM radio and WiFi. IdeaTab S2110 goes for $399 in USA. The A2107 runs Android 4.0 ICS and features a 7 inch display, a microSD card slot, Bluetooth 4.0, RM radio, HD display and it will have a WiFi and 3G model.
