The veil of secrecy over plans by Sony to market Tablet PCs, and booming in recent years, can reveal recently published patent application is a Japanese manufacturer. It describes the concept of e-book with two touch screens, which, however, able to take shape, turning into a laptop. In addition, this device can be used to recharge the solar energy. 

The lowest screen should play the role of the keyboard, and the top will display the content. It is interesting that something like we saw in October last year at Ceatec 2009 exhibition, where Sony has brought some of their conceptual designs. Also described in the patent, the device resembles a tablet design Microsoft Courier, on which work has now been discontinued.

While Sony's patented design does not always find their embodiment in actual products, new patents have already confirmed that Sony in recent years has worked to create a Tablet PC. Thus, the presented concept can become a model for further development, unless, of course, the Japanese manufacturer choler seriously compete with Apple and its iPad
