ah yes i forgot to mention that; i've unlcean shutdown both my laptop and netbook more times than i can count... no issues. from the btrfs list, most people seem to have problems with unclean power down only when other layers/indirection are involved, like dm-crypt, etc.
This is not surprising. ZFS can also have problems when put on top of some other system. These filesystems are made to be on the bare drives and generally to provide their own raid/lvm interface (though btrfs doesn't yet have a full raid implementation like zraid on ZFS).
I have been running ZFS on an SSD with /, and an HD with subvolumes for /var, /tmp, /etc and /usr without any problems. Quite fond of subvolumes too, it seems like a good way to break up and even limit a directory's space without having to create a ton of separate partitions. The issues seem to be related to a few usage scenarios, and will of course continue to get better with every kernel release.
