Given I have (to the best of my knowledge, anyway) no way to play or read a bluray disc, and never had have, it's tricky to answer the question "Do you still buy blurays" - in much the same vein as you can't really answer the question "Do you still beat your wife?" I have never bought a bluray, and I'm pretty sure I never will. The only time I've watched a film on bluray (the new Tron), I kept getting distracted by how "uncanny valley" it was....
OTOH, I still frequently buy DVDs, particularly box sets.
