Aside from looking at the ink, none of these things actually have to do with reading. They're all things that deal with paper. I've never seen them as important, though I understand that some people enjoy them. But so much that you cannot read without it? (Or at least so much that it makes reading significantly less enjoyable).
To me, that's like someone saying they like eating popcorn while watching movies, and that they could never watch a movie without popcorn. Do you really even enjoy the movies, or just the popcorn?
I also have a vinyl record collection. I really enjoy the ritual of setting a record on the turntable and playing it, studying the packaging and any inserts included while it plays. But 99% of my music listening is done through Spotify or Bandcamp.
eReaders have so many advantages aside from just space. I never lose my place, even when reading 5 books at once. I can highlight what I'm reading without worrying about it being harmful to the book. I can look up a word in a dictionary instantly, on the device (this ended up being a much nicer feature than I thought it would be). Being able to easily read with one hand. My library is entirely backed up online, so if I lose or break my device, I still keep my books (this isn't so true about the collection of books I left at an ex-girlfriend's house).
>I think it boils down to the actual experience
Certainly. It just surprises me how many people seem to enjoy the experience of reading more than the actual reading.
