Smartphones compete on camera quality, but manufacturers rarely, if ever, advertise the quality of their microphones.

Rich Warren | UI professor weighs in on 'toxic chemicals'

A couple of weeks ago, I wrote that picture quality is in the eye of the beholder. A month ago, I declared that halon gas as found in a fire extinguisher is toxic. Apparently, toxicity is in the lungs of the beholder. We received this email from a University of Illinois chemistry professor:

Rich Warren | Comcast store can offer advice on picture quality

Seeing is believing, while numbers can lie. What you see is what you get. A month ago, I advised readers to buy a new TV, since current 4K models look so much better than TVs from a decade ago, while costing less. A reader disputed my rosy recommendation:

Rich Warren | Advice to deal with lithium-battery fires

You are about as likely to win the Illinois Lottery jackpot as to experience the lithium battery in your car, smartphone, laptop or any of hundreds of other devices catch fire.

It seems that between Amazon and Google, along with other players, privacy becomes as endangered as a lone swimmer in a riptide.

Rich Warren | You don't have to settle when it comes to sound

The audio train careened off the rails. When I first rolled down the sonic tracks, only quality mattered. As a student at the University of Illinois, the sound quality of one's audio system determined dorm floor prestige. In 1977, when I began writing about technology, my columns focused on the best possible sound at home and subsequently in the car.

Rich Warren | Some sound advice on buying a receiver

Let's open with a reader question: We are setting up a TV area in our basement. I have a couple of vintage Polk audio speakers that I plan to use for a TV sound upgrade.
