I wasn't using the disc service much anyway and my daughter using the streaming a lot, so I just dropped down to the streaming-only plan. I mainly get BDs from Red Box and occasionally from Blockbuster.
I disagree with the general sentiment that streaming is inherently terrible. Anyone who believes that needs to watch a 1080p HDX movie on Vudu. It is better than broadcast HTDV and almost indistinguishable from BD. Almost. At any rate, it is very, very good. Netflix is not quite there, but is getting better over time.
My daughter uses it to watch a lot of anime. It is FINE for that. We've also used it to catch up on TV shows we missed. Again, fine. It is 720p for goodness sake. To hear some people talk, you'd think it was 320i. We use it to watch the odd movie. I gotta tell you, I wasn't pining for 1080p watching Pricilla, Queen of the Desert. Do I want to watch Iron Man on my 67" TV via Netflix Streaming? Hell no, but it would kick ass on a tablet. It is all about context.
