ASUS has itself plenty of interesting kit at CeBIT '09 - including the Lamborghini VX5 notebook and sumptious Eee Keyboard - but there's arguably nothing as revolutionary as the Eee Book concept.
Pictured below, this technology showcase is essentially a slim netbook-like form factor that incorporates two large touch-screen displays. The working sample at ASUS' booth features Windows 7 as its operating system, but ASUS personnel weren't keen on the idea of letting us try out the virtual keyboard.
Nonetheless, we're pretty certain that we couldn't do away with our tactile keyboard completely. The idea here, of course, is that the Eee Book can be rotated - aided by a built-in accelerometer, we presume - and be used as a book-like device.
Certainly an interesting concept, and it brings a whole new angle to the increasingly-popular electronic reader market. Sadly, ASUS has no time frame for when - or indeed if - such a device will reach mass production.
