It probably depends on who the customer is and where they live.
In urban areas where there are multiple options for broadband, bundling is the holy grail because it's multiple services provided on the same infrastructure (making it very profitable) and it locks a customer in to where they are more resistant to defecting to the competition. Where I live, I have a choice of cable, DSL and WiMax, and the competition is fierce. In the sticks, it's a very different situation.
Personally I don't like bundling; I don't see it as a very good deal. Comcast (my broadband provider) continually tries to sell me their phone service, which is barely cheaper than my old land-line with AT&T, and exponentially more expensive than my VOIP service. The broadband rates have been static, but the basic TV service creeps up every 6 months or so. I am getting closer and closer to defecting to an antenna/broadband solution for television, since the value I'm getting for the TV portion is poor, and deteriorating.
AT&T sends me so much mail (at least 1 piece every 2 or 3 weeks) that I'm convinced that they'd make more money if they'd give me the service for free and stop sending me the junk mail.
