iPad case maker Clamcase promises to add laptop functionality to smartphones with Clambook-- an ultra-thin processor-free laptop connecting with Android and iOS devices.

The Clambook has a MacBook Air-style look, with a thin aluminium body, widescreen display, 3D Cinema Sound, wireless QWERTY keyboard and multitouch trackpad. It connects to smartphones via MHL cable, meaning it charges the connected device when in use.

While looking and acting like a laptop, the Clamcase has no processor or RAM of its own-- the smartphone handles all actual processing.

The keyboard features dedicated Android keys for media control and app access, and the trackpad supports scrolling, pinching, zooming and 2-finger swiping.

Clamcase gives few other details on the device-- the only available Clambook pictures are actually renders-- but the company says it will be available from Q4 2012.
