Technology has moved into every room of the house—except the bathroom

I’m lying in bed today trying to recover from my annual bout with a malady that strikes me every January around this time like clockwork. It’s no joke: My symptoms include coughing, sore throat, headaches and, ahem, intestinal distress. The direct and proximate cause of my illness is the Consumer Electronics Show, which draws over 150,000 attendees—each of them bringing a truly exciting array of microbes from every corner of the map.
