I'm not thinking about getting it because I think I need some extra, fancy-schmancy service to make a home network. I just like the extra speed I get. Good DSL in my area costs around $49 per month for DHCP and 1.5Mbps/256Kbps. Comcast Home Networking costs $52 per month for 2.5Mbps/256Kbps and a static IP address. Comcast Home Networking, to me, seems like a better choice.
I had a feeling the router they would give me would work if I hooked it up to an AirPort and made my LAN that way. I just don't want to get all off into this project and find out I've wasted my time and money.
