Looking to drop my landline. Do you need your landline to have DSL?

[Harry Monroe]

I've heard it both ways. Some people tell me you need a landline to have DSL, others tell me you don't. I'm reading up on DSL in Wikipedia and there is something called dry-loop or "naked" DSL which doesn't require a landline. The article also goes on to state that AT&T is now obligated to offer naked DSL to consumers due to its merger with SBC Communications. Of course, I don't think AT&T is going to advertise this fact. I've got an AT&T landline (taxes and fees on the landline are more than I pay for the landline itself!!) and AT&T Internet DSL service. Can anyone enlighten me here?
