If btrfs should be considered as the default filesystem for

maturation over the next 5-6 months. I personally would enjoy to
see btrfs to be default sooner than later:-)

Me as well, but right now, i.e. as of kernel 2.6.35's current state of btrfs, it would be a bad idea, I have seen issues here that cause dataloss and on-disk corruption that needs a reformat to fix it, as btrfsck can only diagnose the problem but not repair it, not even with losing the affected data.
In my case, I'm running btrfs on a partition that does heavy ccache-backed compile runs (Mozilla applications) and rsync it daily to a partition on a different disk with a more stable fs, and if corruption happens, it's almost exclusively in the ccache dir, which can be nuked without thinking twice, so I haven't actually lost data. I know this is still experimental, after all.
But from what I've seen, I can't recommend it for important data yet - I surely hope we'll get there, though!
