While I certainly am a big user of OnDemand with my cable provider, and will be if and when I switch to FiOS TV, I for one wouldn't like having my only option for television watching be OnDemand. Sometimes you just want to put the TV on and not have to pick and choose everything you watch and let the network run the programming for you. This is especially true when you have some friends over and you like having the TV in the backround.
