Lenovo has officially announced its latest addition to the tablet market, the IdeaPad S2109. The new Ice Cream Sandwich slate measures 8.9mm thick and takes a page from the iPad with a 9.7-inch 4:3 aspect display, rather than the 10.1-inch (16:10) form factor most Android tablets in that size range. It also sports the same 1024 x 768 resolution of the previous generation iPad (The new model sports a 2048 x 1536 resolution).

Technical specifications include a 1.3-megapixel front-facing camera, four SRS-ready speakers on the back, 10 hours of battery life, and ports for microUSB, microHDMI and microSD. Lenovo hasn't revealed what processor or how much RAM the IdeaTab S2109 will be using, but according to a source talking to Engadget the device is powered by an OMAP4 chip and we assume it will carry 1GB of RAM.

Lenovo is also touting the tablet's unibody construction and "gunmetal" finish, though there's no mention of whether it's actually metal or not. The battery inside should be good for 10 hours of runtime, according to Lenovo. The tablet seems to offer users a clean, unskinned Android 4.0 ICS experience, with both Google Play and Lenovo's own app store available for downloading third-party software.

Unfortunately other details such as price and release date remain under wraps.
