Truthfully, I rather like not having a window behind me. I see several posters in this discussion who sound like that is preferable. Maybe we have a paranoid streak our just don't like people looking over our shoulders. The fact I handle some confidential information also makes me happier to not have a large viewing port behind me. Plus, I suppose I've seen one too many horror films and already had a "only idiots in horror films do that" moment.
