I just don't think saying "I don't own a TV" has as much of an impact as it might have 10 years ago. I think it's OK to have a TV. It's good to watch your local news station and catch up local activities. It's nice to check the weather channel and have the local news stations for severe weather. I don't own a huge TV. In fact, I love my little TV. I've had it for over 4 years now and it's been great. It's easy to transport and doesn't take up a lot of space. My TV hasn't been a money sink and for the past year and a half I've barely paid more than the cost of electricity to run it.
Side Note - Tonight was the first night of the Late Show with Stephen Colbert. I plan on watching this regularly as I regularly watched the Late Show with David Letterman.
