According to this report many universities are at least considering getting rid of land lines in the dorms.

Some of my best and worst memories of college was the phone. At Ball State, we shared one phone between two rooms. It sat in the wall (literally) in a box with doors on either side. Of course those doors didn't seal the box from the other room, so the smells from next door were always seeping through. My "phone-mates" were heavily into weed and I learned what it smells like mighty quickly!
