Sony's delayed entry into tablets should include more than just one model, sources said Monday. A second Android 3.0 model, the S2, would take advantage of Sony's dual-screen patent to create a unique ovoid, book-like model with two 5.5-inch displays. The Engadget tip suggested it would behave like a more advanced version of the Kyocera Echo and run apps that use the separate screens, such as Gmail showing a message list on one and the actual message on the other.
