We have what's called naked DSL or dry-loop (it's de-coupled from phone service). At least in my market, the phone company's system still uses phone numbers for everything so there is a phone number for the account but it doesn't function and you can't plug a phone into it. The FCC has mandated it as a concession during large mergers, so it's available pretty much everywhere in the country.
According to the CDC, as of June 2010 about 25% of US households have no wireline phone but have at least one mobile phone.
This comes up every election year because of the prevalence of phone based opinion polling. Younger people are more likely to not have a land line and thus not be polled, etc etc.
