The Kohjinsha Dual Screen DZ Series was at one point a concept but it has now somehow managed to get itself up onto retail shelves. The dual screen DZ series laptop packs dual 10.1 inch LED backlit display screens, Athlon Neo 1.6 GHz MV-40 CPU, 1 GB RAM (expandable to 4 GB), ATI Radeon HD 3200, 160 GB of storage, Wi-fi and a 1.3 megapixel web camera.

Those dual screens will cost you, so be prepared to fork out some dough. How much? It costs about 95,800 Yen (or $1,107) and is available in Japan.

Dual-screen notebooks are still popping up and the latest is Kohjinsha’s dual 10.1-inch screen netbook prototype, which was spotted at the CEATEC show in Japan. Just like the Lenovo W700, which started it all, one screen slides behind the other so you can use one or both.

Of course this makes it just a bit thicker than your average netbook. Under the hood you’ll find Windows 7, a 1.6GHz AMD Athlon Neo MV-40 processor, maximum 4GB RAM, and a 160GB hard disk.

The Kohjinsha SX Series UMPC is pretty sweet looking, and packs a lot in a small form. It sports an 8.9 inch touch screen display at 1,280 x 768 resolution, Intel Atom Z520 1.33GHz processor, 1GB RAM, 60GB HDD, Super Multi-DVD drive, Wi-Fi and Ethernet connectivity.

Some other features include an ExpressCard/34 slot, card readers, two USB 2.0 ports and VGA out. The Kohjinsha SX Series will be available in Japan. You can get it in black or white for $1199.
