$40 IMHO. The only reason T is down today is because TELUS reported excellent results. Over 2.5 million shares of T traded in the first minute today as institutions moved their investments from T to TU. TU operates mostly in Canada and is only competitive with T in that area. However they are definitely competitors for investors because they are growing fast.
COMCAST is a very interesting company because it is a "johnny come lately" entrant to the communications business. As such it is free of all the antique equipment that AT&T and Verizon have to deal with. However, it is too small to have that much affect on AT&T.
