I can't say that I'm floored by the news/rumor that OpenSUSE is weighing Btrfs as the default filesystem as SUSE has often leaned towards the experimental even when they were selling boxed sets for use on the desktop.
I personally haven't had great experiences with btrfs on desktop machines, but that was mainly due to the lack of tools included in distributions to deal with things like hard freezes and the like. It sounds like OpenSUSE users have already run into this issue in the recent past regarding the lack of file system utilities as dependencies for using the file system. My phobias regarding file systems that aren't JFS aside, I'm glad to see btrfs getting more coverage (and hopefully more help in development and testing) and perhaps is eyeballed by more distributions for potential inclusion. I'm glad that it's happening and hopeful that other distributions that I'd install for purposes other than 'wonder what this looks like these days' will eventually include it in their repositories with a full set of tools behind it.
