Here's a quick and easy way to decide if you're cut out to be a forensic scientist; flip over your keyboard and shake. If not immediately disgusted by the detritus and DNA that comes sprinkling down, congrats! CSI Milwaukee can use you!
And the rest of you? Take heart. Because revolting, bulky and breakable keyboards could soon be a quaint memory when the last vestige of the typewriter is replaced by lasers and sensors. The Celluon Magic Cube is among the first wave of virtual keyboards to hit the market, a device that projects keys of light on to any flat surface, interprets your finger-tapping and sends each p and q to any Bluetooth device.
Aatma studios in San Francisco took this new reality to an obvious fantasy with a video mock-up of a mythical iPhone 5, using laser projection to make keyboards AND thumb typing obsolete, so get right on that, Apple.
We also take a look at Panasonic's new shampoo robot and a revolutionary way for the weak and waterlogged to actually paddle out and catch a wave.
