Good points.

Something that always had me wondering is the places where I find vinyl records today. There are lots of amateur and professional DJs who are still performing using turntables and digitally authored tracks recorded to vinyl. That sounds like a definite quality loss to me. (Or at least durability of your music collection!)

IANADJ, but it seems to me like there are many replacements for this on the market: Pioneer CDJ-1000, FinalScratch, Ableton Live...
