More Details Emerge About Sony iPad 2 Competitors

Interesting new details about the forthcoming Sony S1 and S2 tablets have emerged thanks to a source close to the company's plans.

Cnet's Christopher MacManus reports that four versions of the S1 will be available at launch - 16GB & 32GB models in Wi-Fi and 3G modes - with the S2 getting 16GB and 32GB 3G models only.

The S1 will apparently have a full size SD memory card which compares very well to the rest of the competition and would allow users to add a 128GB SDXC card for £250 (or a 64GB one for a fifth of that sum).

Also on the deck are a 9.4-inch IPS display, possibly with a 1280x800 pixel resolution, with Sony's own proprietary TruBlack and Bravia display technologies.

The battery life of the S1 is said to be comparable to the iPad 2 while that of the S2 is unknown. Accessories will include a docking station and a Bluetooth keyboard.

Both tablets are expected to be launched in Berlin during the forthcoming IFA consumer electronics show, the equivalent of CES in Europe.

Expect both devices to come with PS3 connectivity, DLNA compatibility as well as features that will allow them to interface with Sony's own products. The big question that remains is whether it will be compatible with Sony Ericsson smartphones.
