I don't have cable or satellite, just a Freeview box (1) - since I can't keep track of all of the channels I get with that, I really can't see much sense in adding satellite or cable.
(1) Note for transatlantic readers - Freeview is the UK terrestrial digital TV broadcast service, I think that there are about 25 channels but I keep losing track. It's "free" in the sense that you don't pay anything over and above the TV licensing fee that pays to run the BBC and transmission network.
