As for so many of my generation the C60 cassette was a mainstay of childhood and teen music experience. Somehow, in a fit of ruthless flint-eyed efficiency, I threw out my many mixtapes a few years ago (and how I rue that moment now).
The nostalgia I feel is for the music, which of course I can buy on the intershops, but almost equally for the physicality of the technology. Let's call it "affordance nostalgia". Now I can have both, sort of, with an MP3 player in a C60 cassette housing. I can even forward through tracks by turning the tape sprocket with a pencil. It's almost real.
