I'm in the non-vinyl camp, but one that wishes he didn't have enough reasons not to.
Reasons for: I love the sound, I love the fact that I can walk into tons of places and walk out with enough music to keep myself busy for weeks and weeks for close to nothing. Same goes for garage sales, auctions, and what not. I love the fact that on the cheap I can pick up a ton of albums and artists I've never heard before, or for which the album is no longer pressed or available on any medium -- that would honestly be the greatest joy for me. I love to try out music that's new or completely foreign for me. Regardless of the medium, to be able to do that on the cheap keeps you trying new things, because you're its not like you just spent a $200 to get ten albums all of which you may despise. For $200, I could walk into a store and buy enough vinyl to keep me busy for a _long_ time. Breaking down that hesitation that keeps you from trying _anything_ in the music world would keep the pure music aspect going for literally forever.
Reasons against: I don't mind minor inconveniences, say in comparison to the digital world at all for primary listening. Thing is I also listen to music in the car, at work, etc. So for any new vinyl I purchase it means that I have to do a vinyl -> CDR transfer, or also purchase a CD copy. That to me is inconvenience and cost, because I would not be able to live with just one medium. I could and probably would deal with this though if the one factor that's kept me from buying a new analog rig didn't exist. What's that?
I'm a renter. I know for example that the home I'm living in now will be sold soon and I'll be looking for a new place. One of my least favorite things in the world is moving. One of my others is not having enough space for living...or having one aspect of your life completely dominate your living space.
I know myself with music, and I know what I'm like when I walk into a CD shop, and walk out with stacks of CDs. In the vinyl world, with the ability to cart home gigantic stacks of records for close to nothing, with the ability to acquire people's entire collections for close to nothing, I know that realistically within 6 months I'd have 4, 5, 10 thousand records in my house...
The thought of the moving process, the thought of potentially not having the space in a new place, and the thought of needing a dedicated room to store it all is just not something I'd like to deal with now.
When I go through with a home purchase....watch out though.
