its now 2 HD streams in Chicago land; as far a PQ is concerned, it will be more a product of your installer and the wiring then ATT itself..
remember, installation is free with no contract, so don't cancel your other services until you are sure you like it..
For me, it will mean saving 80 bucks a month, almost a thousand a year, so, it was a no brainer for me.. I will have to "downgrade" to 10/1.5 internet from my current Comcrap 15/2, but, you never see those speeds with Comcrap, except at 4 am on weekdays.....
I'm saving 60 a month between tv,internet and phone, but much more for the first year with 14 a month off for a year, an additional 20 off for 6 months, another 10 off for 6 months, three months hd programming free(10 a month) and then the 100 cash back. AN NO CONTRACT. My wife and I noticed no downgrade in hd signal compared with our former DISH hd. The sd is actually better than the soft sd pq I had with DISH. The hd dvr is excellent, I like it better than the 622 which was also a fine machine. Two hd streams which is enough for me although the last tech who was here told me that it will go higher at some point.
