In most parts of the US, it's cable we want an alternative to. We generally only have 2 options for internet service: cable, or DSL via the phone company (if you live in a large city and you're lucky, the phone company is Verizon and offers fiber instead of DSL). DOCSIS 3.0 is significantly faster than the DSL options generally are, so there's really only one choice if you want speeds greater than ~50 mbps. Here in northern Utah, my options are Centurylink, which offers ADSL with download speeds of up to 40 mbps, and Comcast, which offers DOCSIS 3.0 with speeds of up to 105 mbps.
