At IFA this year, Kazuo Hirai, president of Sony's consumer products and services group, showed off the Sony Tablet S and Sony Tablet P.

The Tablet P folds in half and has two touchscreens which can either be used together as one large screen or separately as two small screens.

The Tablet S is thicker at the top than at the bottom so it can be easily read when placed on a flat surface.
