The SideShow feature that comes with Windows Vista has been well accepted by users as well as gadget-makers. However the vast majority of desktop users missed out on the feature that was supported on everything from laptops to handbags. Thanks to Asus, even they can enjoy this genius piece of technology. The solution is made up of Asus ScreenDUO to help your desktop system support the SideShow feature. The system is powered by a USB connection to your system. With your PC off you can synch everything from incoming emails to RSS feeds. The device works well with P5B Premium mainboard but may also provide compatibility with other motherboards.

The price and the availability of the Asus ScreeDUO SideShow for Desktop is unknown. However, we hope to catch something from the makers as soon as possible.
