Would you use it regularly, and if so, for what? For the offhand driver installs, you can always use Mac disk sharing.
- ripping CDs of rare or out-of-print music.
- burning CDs/DVDs of photos for friends who don't have a USB drive.
- reading old CDs I have, like a CD of BeOS.
But I use it infrequently enough that maybe a peripheral is the way to go.
