John,

Very informative.  I intend to throw it in the face of the next AT&T 
salesman that comes knocking on my door.  We get one every couple months.

It is especially true that they lie about now being pure fiber to the 
house.  I ask them how they installed fiber without having sent out a 
machine to route it.

Not mentioned is the RFI that their modems can generate.  Reading the 
article confirms that it is almost a given-- especially for those with 
overhead utilities.
