DSL is not an ATT exclusive so when you get DSL, it carries no marketing value. If you get the same service, for the same price but they stuck a new label on it, that's it. A new label.
http://en.wikipedia.org/wiki/Brand goes into marketing a little more. DSL is a COMMODITY and companies don't want to deal with commodities so they'll call it a new name yet it's the same old thing.
Hope this helps,
I've been an ATT DSL customer for quite some time. Now, I've received notification from ATT that my DSL must be changed to U-verse soon. Is it true that when U-verse is available at a particular location that DSL is no longer available? Or is it a sales pitch?
