Volumes do not matter. The point is 100,000 cable modems purchased today cost considerably less than 100,000 bought five years ago, just as one bought today costs considerably less than one bought five years ago. The ADSL modem I was given by BT when on the original BT DSL trial in 96 cost well over a £1000. You can buy the equivalent today in dixons for about £50
As for replacing the cables - the short answer is they do not replace the cables (unless they are cut or something). They put them in once and thats it. End of story. Just as you do not replace the cat5 cables in your office when you upgrade from 10mbs to 100mbs or to 1gbs. Some of the copper pairs used by BT for telephony were put in 50-80 and even 100 years ago and still work fine.
