I have seen the documentary of Sony’s Xperia Touch in NHK (Japanese news network) and I was amazed. It is a small projector, a little bigger than the ordinary hard disk that you can connect to your phone or laptop. But the amazing thing with this projector is that the projection becomes a touch screen. For example, the image is projected on the table then you can use that projection like the screen of your phone. The cost of Xperia Touch is $1,6oo as promotional price.
