I think this is actually the key thing in this discussion.
I left their DSL and phone for Comcast a couple of years ago and cannot be happier. My Internet with Comcast Absolutely Rocks, Uverse just cannot match the speeds I'm getting with cable.
They cannot compete with thin copper on internet speeds, so they are diversifying to video content.
I will never go back to them.
Comcast, (who's service I Love right now) will most definitely take advantage of this in the future and find a way to screw me. And I will have no true alternative.
