Sony has finally (and officially) released its Tablet S and there are currently three versions available on the market, all of which can already be preordered from Sony itself.

Internally known as the SGPT111GB, SGPT112GB and SGPT114GB, the three versions of the Tablet S will be available for £399, £479 and £499 for the 16GB Wi-Fi, 32GB Wi-Fi and 16GB 3G versions respectively, matching the prices of Apple's iPad 2 tablets.

They are expected to be released in a couple of weeks and, as mentioned previously, they share the same configuration as most of their competitors. An Nvidia Tegra 2 SoC clocked at 1Ghz, 1GB RAM, a 9.4-inch WXGA capacitive touchscreen, USB port, a SD Card (rather than SDHC), Wi-Fi, GPS, Bluetooth 2.1 (rather than 3.0), a five megapixel rear camera and a VGA front facing one.

Interestingly, Sony calls the tablet's battery the BPS24, which is also used in laptops and has a 4400mAh capacity, although at least one review points to the fact that the battery capacity on the Tablet S is 5000mAh and should get around eight hours worth of medium usage.

Sizewise though the Tablet S is average, partly because of its peculiar "wedge" design. It is on average 10mm thick and weighs just under 600 grams for the non 3G model.
