They keep trying to make us watch the commercials. If it prevents you from switching channels during commercials, it would make it hard to channel surf, because every time you landed on a channel showing commercials, you would have to wait for the commercials to finish before moving on to the next channel. If DirecTV or Tivo implement this, it will be time to give up TV in my house.
