OOPS, I voted wrong...
We have our main tv in our livingroom. The second one is upstairs in the "hobby room": is used by the kids for looking tv or playing on Playstation 2.
Then there is a 3rd tv in our bedroom, but we NEVER use it. It was installed there 2 years ago when my legs were partly paralysed, so I could watch tv from bed too. But then I got better, so that tv is there for when we get older... .
