Right now I live alone and I have a TV in my bedroom. I love it because it's great for watching movies, but I can see the concern. I used to watch a ton of TV and it got in the way of doing other things in my life.
I would want to read a book, but because I automatically turned the TV on when I walked into the room, I ended up doing that instead. I can see that it would get in the way of having romantic time.
Having said that, I think I would still have one in the bedroom, but maybe not hooked up to cable.
