Z Pen

Once upon a time we dreamed of eating meal-replacement pills while flying our cars to see a holographic movie. While so much of the future's useful technology has failed to materialise, there's one field that has come on in leaps and bounds like an untethered spacewalker, and that's handwriting-to-typing. Finally you can grab hold of what looks like a normal pen, write as usual, then download everything on to a computer as images and text. If it wasn't so ruddy simple, you'd think it was witchcraft.
