We have extremely high-speed internet at home, but I still prefer the quality of the video/audio from Blu-ray discs. Sometimes there’s some stutter with streaming video, and the 5.1 surround sound from a Blu-ray is superior to what I get streaming Netflix.
My wife and I prefer to have both Blu-ray *and* streaming options. Blu-ray is not a “dead tree” media, at least not yet.
Ah, and a lot of programming is only available in disc format, and not available for streaming.
For now. Besides HD quality Video is available for On demand for a majority of the nation. Physical Media is the Buggy Whips of our ERA. It just doen't make sense to waste resources on it when you can Download it and save it to HD. Big Media is pushing hard on Blu Ray but people are not buying in like they did with Video Tape and DVD. Why do so when most can watch HD quality media at the touch of a remote.
