To quote Arjan van de Ven from Intel who works on MeeGo:
we've been using BTRFS in all builds for a long time now, and frankly we have had more
issues with the ext3 side of the world than with btrfs

But that comment is no more helpful either as it doesn't discuss what the issues with ext3 were let the fact that ext3 has been superseded by ext4.
I want to know:
* Why was BtrFS less of an issue? (and what the issues were)
* What were the issues with ext3?
* Would those issues still have existed if they'd used ext4?
* and were the BtrFS issues more technical than the ext3 issues (it's all very good and well saying there were more issues with ext3, but if those issues were easy to fix and BtrFS's weren't, then ext3 will still make a better consumer fs for the moment).
Simply because Ext4 is crap and very slow. Even Ext3 is MUCH faster than Ext4. Btrfs is quite usable already and already outperforms Ext3 and Ext4 in many (most) tests.
Also, just because a distro makes some or other filesystem the default, doesn't mean you as an end-user needs to you use that default. The installation allows you to choose any file system you like.
And when in doubt about a file system, do what I do. Make one of your non-bootable partitions (eg: /opt) the file system in doubt. Then play around with it, copy/read files from it, play movies form it. Do software compiles from it. If it doesn't work out for you or doesn't perform to your expectations, simply copy the data off and reformat that partition with a different file system. It's not that damn difficult.
I think Ubuntu has a good idea. Put Btrfs out there so it gets some exposure - that's the only way software improves really fast.

From April, but the general consensus is that ext4 is the best overall filesystem.
And a big warning is there too. DO NOT ATTEMPT TO RUN postgreSQL on BTRFS. The one real life example, btrfs chokes and dies on (doesn't crash, just crawls).

They just changed to Ext4 as the default in new installations of 09.10. Why would they switch so soon, especially to something not so ready?
