Sony is planning a tablet computer with a touch panel similar to Apple's iPad for later this year that the Japanese manufacturer promises will make the best of its gadgetry and entertainment strengths.

The product code-named S1, shown yesterday in Tokyo, comes with a 9.4-inch display for enjoying online content, such as movies, music, video games and electronics books, and for online connections, including e-mail and social networking.

Sony, which boasts electronics as well as entertainment divisions, also showed S2, a smaller mobile device with two 5.5-inch displays that can be folded like a book.

It did not give prices. Sony Corp Senior Vice President Kunimasa Suzuki said the products will go on sale worldwide from September. Both run Google's Android 3.0 operating system.

The announcement of Sony's key net-linking offerings comes as it tries to fix the outage of its PlayStation Network, which offers games and music online.

It is unclear when that can start running again. Sony has blamed the problem on an "external intrusion" and has acknowledged it would have to rebuild its system to add security measures and strengthen its infrastructure.

Suzuki said both tablets feature Sony's "saku saku," or nifty, technology that allows for smooth and quick access to online content and for getting browsers working almost instantly after a touch.

"We offer what is uniquely Sony," Suzuki said after demonstrating how the S1 was designed with a tapered width for carrying around "like a magazine."

The devices will connect to Sony's cloud-computing based library of content such as movies and music, as well as to Sony PlayStation video games adapted for running on Android and digital books from Sony's Reader store, the company said.

Sony, which makes the Vaio personal computer and PlayStation 3 video game console, has lost some of its past glory - once symbolized in its Walkman portable music player that pioneered personal music on-the-go in the 1980s, catapulting the Japanese company into a household name around the world.

It has been struggling against flashier and more efficient rivals including Apple Inc with its iPhone, iPod and iPad machines, as well as South Korea's Samsung Electronics Co, from which Sony buys liquid-crystal displays, a key component in flat-panel TVs.

Sony has already promised a successor to its PlayStation Portable machine for late this year, code-named NGP for "next generation portable."
