I beg to differ.
Reliability is quite important at home, where one has umpteen years of digital pics, digital video, digital music, documents, yadd yadda, etc all saved on fallible harddrives.
Being able to put 3 (or more) drives into a home system, setup a raidz config across them all, and setup nightly snapshots via cron is *hugely* awesome, useful, and usable. It's the non-Apple version of Time Machine.
All that's really missing, is an easy-to-use GUI management tool for creating storage pools, filesystems, and accessing files in snapshots. Once someone comes up with that, and people start using ZFS, we'll all wonder how we ever managed storage without "storage pools", "inline, infinite snapshots", and all the other fun features. And those features will start cropping up in other storage management systems and filesystems. (DflyBSD's Hammer fs has similar concepts, as does Tux3 and Btrfs in Linux-land).
We're using ZFS (and rsync) on our backup server at work, doing remote backups for 35 servers. And the nightly snapshots feature has already saved our bacon twice (once for an accounting file, once for someone's e-mail account). Been running it at home for a couple months now as well. Haven't had to use the daily snaphots for anything yet, but it's nice knowing they are there, along with the raidz redundancy, for when I will need it.
