I'm up near 100% - assuming I can include my ripped movies and TV shows, which are "streamed" from my media server (an old Powerbook) to my television. If not, I'm still in the 60-80% bracket. My daughter's taste in movies and TV shows is similar to mine, and so she has pretty much the same viewing habits.
I'm not at 100% because we still watch (via Tivo) a few old TV shows - e.g. Hogan's Heroes and Seinfeld - that aren't always available via the streaming options I've got.
My wife, though, still watches a fair bit of network television - mainly those gosh-awful police procedurals and medical dramas. Some of those are watched on her iPad via the particular network's app, but most are Tivo'ed and watched that way.
