No, it isn't. I'm at a tipping point of canceling my Comcast cable/internet because I don't think it's worth $80/month. 90% of what I do online at home is for entertainment. And I would guess that is the same for most households that don't have a tech worker. (I am a tech worker, but I've finally trained myself to not take work home).
Really the only reason I keep it is because I don't want to deal with griping from the kids.
