My parents have never had one in the house. I've lived without one for 2.5 years now, since I moved back here. There is one outside in the office, but the kids don't really go there.

So no TV, they occasionally get DVDS (on a 10" DVD player) but only on weekends, and only if they're really tired and need a nap!

I can definitely do without it (although I do miss NCIS...)
