And then there's me, with Vinyl. CD won't die for a long time and neither will Vinyl. Magnetic tape, that's really dead.
But that's for music. Data storage with CD is just about dead. I haven't used CD for storage in a while but I still have a drive in my PC for watching movies and burning CDs I still use DVD for bootable OSes for old PCs. I don't know about you guys, but I really like seeing an old G3 mac or a pentium 3 tower booting into something I can use :)
