Now that I own a house I have a few favorite CDs that get frequent listening, but still no blurays, mainly because there’s not much I rewatch often enough for owning them to make sense. If I went out and bought everything I could justify right now I might have maybe 5-10 tops.
It’d be cool if a physical medium that’s sized similarly to regular SD cards caught on. You could keep a decent number of albums or movies in a case the same size as a bluray/DVD case, or a full-on library in something similar to an early 2000s portable CD flip case.
