Robotic dogs, sunglasses with a built in radio. It would sound like I am talking about Sony's Aibo or Oakley Thump sunglasses, but I'm not. In fact, what I am talking about goes way back to the 1960's.

Consumer Reports has a nice archive of tech over the years...and in this case not so good ones. Pictured above is Gaylord the Pup, and he used up four D batteries in just over 2 hours. At that rate, a real dog would be a more affordable option. Thankfully, forty years later and we have yet to be over run with electronic pets.
