For many years I worked as a typesetter (typographer) and a proofreader for various design agencies and publications. I was trained on an early cold-type machine called the Editwriter, and it's all old technology now. But in the early 80's it was the red hottest up-to-date technology and it's what I learned on.

I've owned several desktop and laptop computers since then, and every one of them has/had a mouse and keyboard) as primary interface tools. It's a brilliant, ubiquitous tool!
