Do I still buy DVD or Blu-ray discs?

Yes, but not nearly as frequently as I once did. Price is the main reason. Now, I buy mainly Blu-ray. I prefer the video and sound quality over streaming. I'm a big fan of special features added to discs. Having said that, I do see the future leaning toward streaming video, etc., and personally I'm saddened. Dump DVD format, lower the retail prices, add more features, and I'll buy more.
