sick of rebuilding ZFS 10+ times a month; is BTRFS there yet?

I'm thinking of giving it a shot as the root filesystem on an old laptop. A recent Ars Technica feature says BTRFS is still a hopeless mess with RAID, but good enough if you just want to use it on a single disk. Even snapshots, scrub, compression, send/recv are supposed to be working.

Anybody using BTRFS as their daily driver root filesystem? How long? Any disasters? Any luck converting ext4fs?
