I still have my whole collection of SNES, Sega Megadrive, N64,GC, Wii, Wii U, PS1/2/3/4, Xbox 360, Gameboy, GBC, DS, 3DS and PSvita games. And I will probably never get rid of it because this is part of me you know, have grown with it. I like the physical thing, you can see it, you possess it for real and this is something you can't do with digital copies. I have "a few" games on Steam for exemple, and if it goes down so my games are, nothing I could do.
I'm still buying physical copies of my games when I can (and when not on PC 'cause you just get a Steam or Origin code which is not the same as the game) but not old games. They are expensive most of the time so it depends on the situation.
About VHS and DVD well, I have some but not buying it anymore, most of the time I just watch a serie or a movie once and that's it, still going for those I really like though.
And the books, well, I really like the sensation of a book. Holding it in your hand, felling its weight, its sent. I don't know, books have a mysterious attractive power that you can't just reproduce with digital. Will it be hentai, cartoons, manga, novels... I'm buying the ones I want, reading in shop those that are "a bit interesting" and reading online the ones I can't have (too old, serie not complete, not published anymore or not for an acceptable price, shipments even more expensive than the books....)
Oh and almost forgot, cassette tapes, I'm still using it in my car for long trips :D But I have unfortunately lost the ones with tales for children on it.
I think the digital copies of whatever you may have are something that build your environment, make your home (car, place at work...) yours. This is not about bragging, just about saying "Here, this is who I am".
