We have seen the Asus Eee PC ultra portable device earlier, actually VIA shows a similar product, which is called the NanoBook.
As the name implies, VIA NanoBook is really small. The device is powered by a VIA 1.2GHz C7-M processor, up to 1GB of RAM, a 30GB hard drive. It has a 7-inch WVGA LCD display, WiFi 802.11g, Bluetooth and even DVI-Out interface. It runs the Windows XP.
There is a expansion slot next to the screen, where you can plug in optional GPS, HSDPA modules. The NanoBook weighs less than 850g.
PS. In Taiwan, the device is branded as iDot CE261.
