Re: Services are differentiated.
Switch providers? Where do you live that there is more than one broadband provider?
Maybe in a few extremely high density areas, but in the US, I'd guess north of 90% of folks have no choice for high speed. Your choice is TW, Comcast, or Cox (whichever one has the monoply rights to your area) who do not compete against whatever DSL offering you find at a tenth the speed.
I could go for a multi tiered internet IF their was some real competition. Sadly that doesn't exist for most of us...
