Sony, a laggard in the booming tablet market, launched its first tablet computers in an ambitious attempt to grab the second spot in the market created and dominated by Apple's iPad.
The gadgets will use an operating system based on Google's Android 3.0, said Kunimasa Suzuki, deputy president of the consumer products and services group, as he unveiled one of the devices from his jacket pocket during a media launch on Tuesday.
The tablets called S1 and S2, are WiFi and 3G/4G compatible. One of the models will have two screens, Suzuki added.
S1 has a 9.4-inch display while S2 has two 5.5-inch displays that can be folded. The tablets will allow use of PlayStation games.
Sales of tablet devices are expected to quadruple to about 294 million units between 2011 and 2015, with almost half that Android-based, research firm Gartner has forecast.
