The house I am building for myself I am wiring 3 wires with a phone wire to each side of the room in most of the rooms in the house except a small bedroom that I never plan on having a multi-tuner satellite receiver in. It also does not hurt to have the extra wires because you never know.
Yes I did the same thing besides the RG6, I ran two phone lines to each room, too. Not really an issue with wireless phone systems now the norm and very affordable so they are not being used, at present. However this is a brick home on a slab and it it would take some effort to add in the future. My thinking was that maybe TV would be available though phone lines in the future. If this home had a basement or craw I may not have done all this planning and install since it would have been much easier to modify in the future. The way it worked out it was very cheap to do and became an investment in the future. Very happy with the results.
