Who needs a mechanical keyboard if you can have one made out of lasers with an IR sensor to detect where your fingers are typing?  With both USB and Bluetooth connectivity the Celluon Magic Cube will beam a virtual keyboard onto any flat surface allowing you to type on a full keyboard without having to cart one around with you.  This will be more handy for tablet and phone users but still might be worth using with a laptop just because it is made of frickin' laser beams.  Hardware.Info tried out one of these hard to get a hold of devices and loved it as it performed as advertised and even has a mouse mode.  You may not type quite as fast as you would on a normal keyboard but you will look far more impressive.

"It still looks and feels like science fiction, but this actually works. With the Magic Cube from Celluon you can create a fully functional keyboard on any surface, that types much better than the mini-keyboards on your average smartphone. The added value for tablets is more limited, because for those there are many more alternatives in terms of external keyboards."
