I liked the caddies. They felt very computery which i enjoyed.

My first was a WORM magneto optical drive that used caddies in i guess 1988. They were already pretty cheap by then - $5 per caddy and $6-8 per WORM disc - but with downloads limited by the 2400 baud modem I never really had much to put on em! It played compact discs and read CD-ROM media as well so mostly it played the beach boys and Myst!
