This Piper article gives his reasons for not owning a TV.
It's a model of careful, nuanced argument. He has strong views on the matter but he rarely overstates the case, which is cool.
I like his point about not wasting your life. I think there's a fair point on the triviliaty of television, although I there is a lot of intelligent television and also a place for lightheartedness in human life.
Isn't it great haven't people like Piper and Driscoll hanging out in the same room? It forces us to think through an issue very thoroughly.
