The Fujitsu Lifebook Concept unites a laptop, tablet, phone and camera together in one device. Even if we've seen devices that come close, this concept takes the cake when it comes to multi-functionality. Where a keyboard would be, the laptop holds a small tablet. As soon as the tablet is in the slot, the tablet itself becomes a full size touch-based QWERTY Keyboard.You can detach its camera and use it as a digital camera, detach the tablet and use it as such or attach it and use it as the laptop’s keyboard or touch drawing area.
