I'm definitely old fashioned, and I don't do multiple layers or 40 pin chips. I'm also the kind of person who, when first viewing a CAD program rotating a stick figure, wondered, "Why does anybody need that? Can't everybody do that in the air in front of their face?"
Well, I'm wiser now. My new rule is, "As soon as you can't hold the whole project in your head, you get a piece of paper", but my projects still haven't exceeded my ability to visualize, so I don't go get a computer when I need a drawing.
