Really...there are hundreds of apps for those as well. I'd think weather and news would be the last thing you'd look to basic cable for. As a cord cutter for several years now, the only rationale I can find for continuing the Comcast train is sports. Movies are passe on live cable (want some movie with those commercials?) High-demand TV series are another, but many of them show up via on-demand services not long after broadcast (w/o commercials) -- or can be had by "other" means.
The cable + sports networks have people in a headlock, though. Want to sign up for Big 10 football? You must have Comcast. A lot of other sports networks are similar. The minute sports goes to an a la carte or subscription model that doesn't require a cable package, I think it will signal the death knell for big cable.
