"The keyboard is still the predominant way we interact with a computer. Voice input, touch screens and even whole body gestural input may be on the increase but most of us still type our commands or data into the machine. This makes is all the more surprising to observe how many programmers use just two fingers when confronted by a keyboard and use the time honoured "hunt and peck" technique. It isn't stylish and it isn't efficient. Imagine if a musician picked up a guitar say and then proceeded to play using just one string at a time. You'd have to conclude that while they might be musically brilliant they just hadn't taken the time to physically master the tools of their trade. And what else is that keyboard but the main tool of our trade?"
