New formats are going to come and go ... digital is about convenience and transportability, which means that we're headed toward a non-physical-media digital world. On-demand and downloadable entertainment will be the norm sooner than you think.
Moreover, I'm looking at CDs of mine that I've had for 10 years or so ... the substrate is decomposing somehow. My Kieth Jarret "Sun Bear" collection is totally unplayable! Scratches on CD are way more annoying than on LP, and CD seems to be more easily scratched. YET ... I have 60 year old records that sound FANTASTIC.
More and more new vinyl is being released, there's plenty of old vinyl to enjoy, and it doesn't take much to get back in. The rewards FAR outweight the risks.
