Yes you do. Instant backups (snapshots) alone are worth the investment. Take a snapshot before you update your kernel, and poof super-simple recovery. Working on a project and need to access it remotely? Take a snapshot and then pull it to wherever you are, your dev environment anywhere. (Different use-case from GIT.) Snapshot /home/ and worry less about computer migrations. ZFS is _THE_ power-user tool of the decade hands down. Disclaimer: I run FreeBSD on my workstation, laptop, and servers. I've never tried to "mix & match" FreeBSD & Linux ZFS implementations.
