I am going to have to disagree with bananarama here. It IS what you do and NOT the way that you do it. If an architect spends his time considering his choice of pencils he's either in the wrong job or bored with his current project
Creative flow is easily disruptible. A programmer having to use a different editor, or becoming conscious of a different keyboard than the one it replaced is disruptive.
He may want to use the right pencil, the one that feels right in his hand so he can muster the subconscious forces that drive his talent.
Programmers are no more assembly-line workers than architects.
