For me it's similar to the reason why I like having a mechanical pendulum clock on my wall. A quartz clock keeps much better time, but there's something cool about being able to see the gears turning. Vinyl isn't quite like that, but it's a lot closer than an MP3 player. There's also something about the imperfections of vinyl, the noise, clicks, and pops, that is a valuable part of the experience for me, probably because I came of age in a pre-digital world.
