AT&T in Dallas
One thing not mentioned in the article is that AT&T world HQ is located in Dallas. This is really a shot across their bow.
I happen to be just over a mile down the street from that HQ. The best "broadband" (hah!) DSL service they were able to deliver to my address was just under 3Mbps, with lots of down time. Fortunately a local company installed a fiber backbone in the neighborhood, and I now get 50M promised / 100M actual for just $50/month. If Google can do that for the whole city ATT will be in a world of hurt.
