I have several TV's around the house, but don't watch any of them that much. I enjoy restoring old vintage electronics, so I've got some old 50's and 60's era TV's that I have restored to working order. In my living room, I have an LCD projector that's connected up to a DVD player, but is not connected up to anything to receive programming. That's where my friends and I hang out to watch movies and stuff.
As far as watching any sort of off-air programming, I have a Dish network box with the basic service in my office, and it's shared between the office and my bedroom. The TV in my office is actually a professional grade TV monitor from a studio. I end up using it to edit camcorder footage on more than watching TV. The bedroom TV gets the most amount of off-air viewing, but even then, it's not much. A little bit of news in the morning to see what the weather is like, and I'll watch some documentaries on it occasionally. I guess I don't get my money's worth out of the Dish network subscription, I only watch probably a few hours of TV a week on it, but it's nice to have when I want it.
