Really, it comes down to service and price vs. speed, I believe. I had DSL through Verizon, and found the tech support and service lacking, especially when my service went down. In fairness, this was 1999 when Verizon had just started DSL service. I switched to Earthlink DSL, which had me connecting with three companies... -Earthlink, for service, support, billing, email server etc. -Covad, for the actual pipeline -Verizon, for the 'last mile' copper connection ...so when I tried to move (to another apartment in the same building), Earthlink told me I'd be without high-speed service for _6 weeks_ while all of the entities got in sync to make the switch. (Not a six week order, as I called almost two months before my move. After the order was in, I would be w/o high speed for that long as Earthlink would have to cancel one 'account' and start another w/Verizon on the same phone #.) So I called Time Warner and was told they could hook up cable modem service in _3 days_. I switched and have found their service to be great. And, at least in NYC their price is better than Verizon for the same speed residential service.
