When we moved into our house, we walked around thinking what are we going to do with all of these phone lines and outlets? After we had Dish Networks installed, we were sitting around one night, seeing what new movies we could download and watch - needless to say, you need a working phone line in order to do so, as we were SOL, we gave up and played some playstation.
Oddly, almost 3 years later, the phone outlets are still here, we really should remove them sometime.
