The 3G-enabled versions of Sony's Tablet S and Tablet P devices are expected to make their entrance into the Japanese market by the end of this month, about six weeks after the WiFi-only models were introduced. The prices of the two slates were not announced, but NTT DoCoMo has made official the October 28 release date. Sony's Tablet S is a 9.4-inch slate powered by an Nvidia Tegra 2 SoC (system-on-a-chip) and includes a 5MP rear and a 0.3MP front facing camera, Bluetooth 2.1 and 802.11 b/g/n wireless connectivity, special remote capability that enables it to control HDTV and other devices, as well as a non-removable Li-Ion 5000mAh battery. The screen has a resolution of 1280x800 pixels and is available in three versions with storage capacities ranging from 16GB to 64GB. As far as the Tablet P is concerned, this uses a rather unique design that relies on two 5.5-inch folding displays with a resolution of 1024x480. A special button allows users to switch between a mode that stretches the images across both displays or just on one side of the screen. Specs wise, the Tablet P features the same 1GHz Nvidia Tegra 2 SoC as its older brother, but comes with just 512MB of RAM, 4GB of internal storage space, and a 0.3MP front-facing camera. A micro-SD slot is also included. Both of the Sony tablets run the Android 3.2 Honeycomb operating system and come with DLNA compatibility. In addition, the Tablet S will also get support for Sony's Video and Music Unlimited services, which enable it to access a wide range of video, music, and e-book stores, as well as for the PlayStation service. Right now, we don't known when the 3G-enabled versions of the two Sony tablets will make their appearance in Europe or the US.
