I'll try. I'm a recent convert.

1. I spend so much time with computers and virtual things, that there's something about the physicality of the thing that's incredibly refreshing.

This is the same reason people like fountain pens and watches. Do you need a watch when you always have your phone on you? Not really, but watches are cool.

2. Sound, which is tricky because it doesn't sound better. Vinyl has different strengths than digital music. When its done well, the artists will master the music to play to those strengths. There are albums I have both mp3 and vinyl versions of that are distinctly different versions of the same idea.
