Funny about the name. I picked it up off my shelf to confirm the quote and got the author wrong. Amusing. In the book, Norman says exactly the same thing. That people are looking for something to achieve some goal, and the hole and, consequently, drill are just means to that end. Of course the spirit of the quotation is different. It means "serve the ultimate goal, not the task chosen to achieve that goal", so it encompasses this with some degree of rhetorical flourish.
