If you’re bored of 16:10 Android tablets, there’s a 4:3 unit out there and it’s not even the iPad. Lenovo’s IdeaPad S2109 has just hit the FCC with a 9.7 inch slate with 4:3 aspect ratio and apparently it’s coming to the stores pretty soon. Specs have also slipped and you’ll read them after the break.

The device uses an IPS display with an unknown resolution, a TI OMAP chip, 4 SRS speakers and Android 4.0 as the OS. There’s also a microSD card slot on board, as shown by the FCC sketch. Engadget has a tipster that informed them regarding this tablet and he said that the mysterious Lenovo device will be released sometime this month. FCC lists quite a lot of countries, including the USA for the debut of this slate. This seems to be a model in the Lenovo IdeaPad S2 range, that also includes the IdeaPad S2 10, announced earlier this year with a dual core Snapdragon S4 CPU.

At the time of the announcement Lenovo bragged with 20 hours of battery life, but we haven’t heard anything since… Will this new model have an incredible battery, too? I wonder if this is a quad core affair, or yet another dual core tablet that represents the new wave of Snapdragon-based slates instead of Tegra 2 ones.
