Yes I do, and thats the case for most comcast customers.
Cable internet alone here is ~$58. Cable internet when you have any level of cable television service is ~$43. Basic analog cable tv is ~$8. Its a "doubleplay" discount.
In some areas the basic analog (pretty much just locals and a few other uninteresting channels) isnt available or its $10-12. It still comes out pretty close to the same or some savings.
It does have some uses. I hooked up an old series 1 tivo to it in a room that doesnt have a satellite run and put all my sons PBS shows on it, along with a wishlist for kids animated movies and he watches that. If my cable internet goes out, I can flip on the tv in there to see if the cable tv is working. If its out, the whole cable is out. If the tv is working but the internet isnt, its something in comcasts routers/dns/etc. And if the directv part goes out during an important live event, we've got a warm backup.
The bennie for comcast is that they get to count me as a cable tv subscriber for the purposes of advertising and competitive stuff, even though we really dont use it.
If you have cable internet, call up comcast and ask them if they offer basic analog in your area, and if there are any discounts for either the internet, the tv or for both. Chances are they'll offer you a promo for six months @$19 for the internet if you sign up for the tv. One thing you might get whacked on is they might charge you an install fee to come out and remove the filter trap that keeps you from seeing the tv channels.
