I still use DVD/BD/4KBD/CD/R2R and yes also Cartridges
I do use emulators, i use steam but i do prefer physical media, i do prefer real manuals and i like boxes. I do like holding something in my hands.
I recently got into comic books (batman, superman, that stuff, never was into it as a kid for some reason, took me a long time to really get a taste for it i guess) and i could've gotten everything on kindle for a fraction of what i paid, but when i hold that fucking 3 kilogram monstrosity that is "Batman Adventures Omnibus" in my arms like it's a baby, yeah, i know why i prefer that medium. Also nobody can alter it or kill it (like Amazon did with 1984 on kindle, Ubisoft did with The Crew or music services only having remixes or remasters on service instead of the original music or Rockstar did with the current versions of the old GTA games)
With movies the advantage is even bigger since the bitrate on most streaming sites is disgusting and not any better than high quality DVD (Amazon Prime has movies with 2 Gigabytes, 1080 and everytime the pictures goes black you can count the pixels like it's a Atari 2600 game)
