I'm generally not zealous in either way of the good old time or everything old is bad... But seriously, have your vinyl and be happy, I am buying CDs for home use (even in a car it got annoying fast). But why would I ever go back to something huge, clunky, fragile like MCs (or MDs to a degree)? I'm not saying stop using a dedicated music player (although I've been team mobile phone for music (with mp3s) forever). But the only reason I see for exchangable media would be trading playlists with friends (I hardly did that with MCs or CDs, but ok) - but why not cheap small SD cards. Why do people want their Walkman back? I just don't get it.
