Along with a pair of Android 3.1-based tablets, Lenovo has unveiled its plans to release the 10.1-inch Lenovo IdeaPad Tablet P1, powered by the 1.5GHz Intel Atom CPU and running the Windows 7 OS. Despite the fact that this system is not as tablet-tailored as Android Honeycomb, and Windows 8 has already been revealed as a touch-optimized OS, Lenovo apparently believes there still is a market for a Win 7-based tablet. The device is due out in the fourth quarter of 2011.

The IdeaPad Tablet P1 features a 1280 x 800 capacitive touchscreen with multi-touch, which can also be operated via a stylus. There's up to 2GB of DDR2 memory, and either 32GB or 64GB of internal memory (SSD), which is expandable through a micro SD card reader. The tablet comes with Bluetooth, WiFi 802.11 b/g/n, 10/100M LAN, 1x USB 2.0 port and an optional 3G modem. There's an integrated front-facing webcam, although unlike the newly-announced Android-based arrivals from Lenovo, the rear camera is missing.

The tablet is equipped with a single 1.5W speaker, as well as a microphone and headphone connectors. The 2-cell battery is capable of delivering up to 6 hours of battery life. The tablet weighs 1.75 lbs (0.79 kg) and its dimensions are 279 x 14.5 x 184 mm (10.9 x 0.57 x 7.24 in). There's no word on pricing at this point.
