Streaming/Download Or Disc based media?

In the recent news about a possible PS$ announcement there is an interesting debate / borderline flame war about physical discs (blueray) vs streaming and downloaded content. If you are on The Verge and reading this you are at least somewhat techy so this is an interesting crowd to ask. Personally I havent used a physical disc in several years. I have a mac mini media center hooked up to my tv and between on-demand cable netflix and hulu + and a healthy dose of piracy to fill in the missing bits I have not had need of it. I undertand the quality difference and have a nice TV but it doesn't bother me enough to go and get a physical disc.

So I open the floor ... Who uses physical media? What kind ? Do you collect discs or just like the superior video and sound quality?
