I'm definitely staying on AT&T. I realize I'm paying a premium for their network, but there is no T-Mobile service at my home and fantastic AT&T LTE coverage. AT&T has great coverage now in CT. Like with my home, car, iPhone, etc., I'm often willing to pay extra for what I consider to be premium service. I couldn't justify to myself falling back to EDGE coverage with T-Mobile on the roads outside my town to save a few bucks.
