Being something of a techno-luddite, I still buy CDs. Since the type of music I like is not what keeps high-street record shops in business (and they're already an endangered species, so I would buy from them if I could) I usually order them online. There are some good folk/early/whatever CD-selling websites, not to mention individual artists' own, and I think the demand for these will never entirely die out, even if they're something of a specialist interest (or BECAUSE they're a specialist interest). Such things are unlikely to pass out of existence entirely.

Actually "luddite" is a bit misleading. I'm certainly not anti-mp3 and will begin using them eventually. But they're highly-compressed so the sound quality is bound to suffer, particularly when played through room-speakers of any size. I also like the concept of "albums" because of their context-related content and (at least sometimes) dramatic arc. Surely there's room enough for both technologies (they probably said that about horse-&-carriages too...)
