Vinyl LPs have been having a bit of a comeback. CDs might as well. In the meantime...I want something tangible. I can play my CDs, even my r2r tapes, and I can store them. But I've lost whole books when my MP3 player was fried, books I had purchased. I don't have money to toss away.

(And yes, I know that tapes and CDs can deteriorate over time.
