Vinyl - it's all about owning, holding and looking after something. Going to that second hand record shop, record fair, boot sale... spending hours flicking through boxes of old vinyl which used to be loved and cherished by someone else. Finding that "rare groove" that you've been after for years or taking a chance on some unknown obscure bit of Krautrock, Italo disco or Detroit techno. It's marvelling at a Hawkwind triple gate-fold album cover or a rare Japanese import Cure picture disc. It's standing back, looking at your Expidet shelving wall of vinyl and proudly saying "I own that".
Sure, MP3 is cheaper, more convenient, takes up far less room... but it's not a "thing" that you can hold and cherish and bamboozle your children/grandchildren/nieces and nephews/godchildren with, giving them a glimpse back to when "things were better". :-)
