Some quirky stuff were shown at CES and no less is the cool ASUS AIRO, which features a sliding keyboard design that is designed (no pun intended) to impress.
When you open it up, the mechanism slides the keyboard upwards and inwards, and the keyboard literally floats up, supported only by two hinges on the side. The rationale given for the design is that the keyboard typically cover up the processor and motherboard, both of which can run pretty hot being cramped up in there. By using this design, ASUS can create thin laptops that run without melting into a puddle of metallic goo on your lap.
Of course, the picture shown here is just a prototype with no running components inside. But from a purely mechanical and design standpoint, it is a beauty to marvel.
