DOCSIS 3.0 is great and all but i think FTTP is the way every thing needs to go and might as well do it now then have to upgrade twice seeing as how long it takes for the cable and telcos to do ANY upgrades
your right but its cheaper for the 3.0 upgrades. The way I look at is the cable modem will be around for the next 10 to 15 years before fiber will used at a persons home.
