Mr. Protocol goes on a rip

摘要

The invention of the Diamond Rio put an end to that. The first MP3 players didn't have enough storage to hold even one whole CD, but lately, players are being sold that can hold entire CD collections. Of course, remembering that MP3 is a variable-- loss format, the fidelity of the music might or might not be good, but for many people, this just doesn't matter. The big difference between MP3 players and cassette players is that the market for commercially sold MP3s is just about zero.
