i've been without cable now for a month or so. maybe two. i can't honestly remember, because i don't miss it. with over-the-air broadcasts recorded to mu old tivo and netflix and playon streaming to my xbox 360, i can get most anything. since i don't yet have an HD TV, the video quality strikes me as phenominal.
playon also has an active plugin developer community that adds some extras (via C#). i'm thinking i might have a go at rolling up some more channels so i can get the rest of what i had with cable.
