Verdict

The Lenovo IdeaTab S2109 is a 9.7-inch Android 4.0 tablet featuring a 4:3 aspect ratio IPS display with a resolution of 1024 x 768 pixels and 420 nits of brightness. Internally, it is powered by a 1.0 GHz dual-core TI OMAP 4430 processor paired with 1GB of DDR2 RAM and 16GB of internal storage, expandable via a microSDHC slot. Key features include a lightweight 1.28 lb unibody design, quad SRS surround sound speakers, micro-HDMI and micro-USB ports, and a 1.3MP front-facing camera for video calls. Main pros include its solid build quality, wide viewing angles, and a relatively clean, stock-like Android interface. However, notable cons include an underpowered processor that can lead to occasional stutters, the complete lack of a rear-facing camera, and a lower screen resolution compared to many contemporary competitors.
