I'm not ready for streaming and I love my dvds. I can definitely see where in the future streaming workouts could be great if a big company like Apple or Netflix creates a mega site of workouts to choose from, but right now I don't see the value yet since I would have to sign up for multiple instructors to get the variety I want.
