My Comcast cable bill is $45/monthly, and Tivo is $12/monthly. I could hook an antenna up to Tivo and it'd be almost as useful, since I don't watch much crap on cable. I'd lose new Southparks and that's about it.
$45/month for standard no-frills cable is ridiculous. God knows what they charge for HDTV and all that crap that requires black boxes and such.
I know Comcast is trying to do its whole On-Demand thing, but I haven't looked into pricing. Does it cost less than an arm or a leg? HDTV? Just movies, or regular shows too?
