Linux and OS X console: Are you working too hard?

Recently, I had a friend, a serious Linux aficionado, come over and we had occasion to sit in front of my machine while I was doing some console work.

Your mileage may differ for any number of reasons, and if you’re not a technical person, you should stop reading now and just forget your ever saw this post. Really. Stop now.
