Reminds me if the time I was in as CS teachers office at uni getting course changes approved. Wasn't till after I left his office that I realized what was wrong with it. He didn't have a computer. He taught mostly post grad stuff, how to build a Turing Machine etc. that I never took so I didn't get around to finding out what he researched. Any way he managed to have a high level CS job with no computer in his office, well not in plain view anyway and certainly not the centre piece on his desk.
