It's worth noting that as much as we say CDs are "dead," the new Xbox and Playstation can still play CDs and DVDs, and Bluray drives for computers are still being made.
I bought a USB3 drive bay enclosure just so I could put a BluRay burner into it and use it on any machine with USB3. Super-handy; I can point MakeMKV at a recent purchase and within an hour or two have a bluray rip ready to play wherever I wish.
I've experienced numerous beloved shows come and go from Netflix, some which I have no idea where to stream. That behaviour is fine for when I'm effectively channel surfing, but when I have a specific experience in mind it's garbage.
I don't trust buying DRM-laden content from most retailers because of the stories of accounts being locked or purchases being removed.
And then there's that I spend enough time traveling in poor-cellular regions...
I swear, DRM'd streaming just simply isn't suitable for _cherished_ experiences.
