When you have a passion or interest in one thing, your attention is drawn to it when you see it. By that I mean those who are interested in PC's, OS's (Operating Systems) etc tend to be drawn towards them when we see them in the background of interviews, TV and movie scenes etc I remember many years ago, the PC on the Daniels family sitting room in the Aussie soap Neighbours was always turned so you never saw the screen. One day the camera panned too far and you saw a Commodore Amiga hand boot screen.
