These things are a plague, and they are becoming more common every day. 
  New monitors, printers, networking devices like routers and modems, 
high-intensity lamps, and who knows what else all come with them.  I 
counted four of them in our home office alone.  Some have FCC labels and 
some do not.  A *really* bad idea whose time seems to have come!
