Vinyl is outdated, too. You wanna take that one on?
portable cd players are outdated, no? with mp3 players you don't have to worry about switching cd's, cd skipping, and you have a lot more space. plus they're small and can fit in your pocket. since you can rip cd's into mp3's you don't have to buy mp3's of songs you already own.
is there any reason why you prefer a cd player over an mp3 player?
I guess you think the whole world sees things like you do. Fortunately, many don't. Believe it or not, there was a time before downloads ruled the world. Vinyl, tape, and CD's came before that and there's still a lot of that "junk" still out there. ...and, even ignoring the fact that used media can be a great bargain, many people still like them.
Not everyone wants to depend 100% on MP3 devices and even many that do may like having the freedom to be able to pick up a piece of plastic on the road and stick it into a device and play it immediately without going through the process of having to rip it to a computer and then downloading it to yet another device.
And, if I like some of the songs on that CD enough, I'll selectively rip and load them onto my MP3 player and still have the source CD (or vinyl) in my possession.
