I have 479 titles in my disc queue. Of those, 59 are available for streaming. I have 34 in my streaming queue which about 6 don't offer discs.
Netflix will always have a delivery problem. If they ship discs, they have to deal with the post office, who regularly decide not to deliver mine or deliver them late. If they go completely streaming, they have to deal with internet service provider's spotty service. So you can be watching a movie and then suddenly it stops while your internet provider takes a break.
Netflix is fast becoming the AOL of online entertainment.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
