Give it a try perhaps on a virtual machine. I've seen it come a long way just over the past two years. While I wouldn't yet run anything mission critical on btrfs, I think the day is coming before too long when it becomes the filesystem of choice. I believe SuSE may be headed there already, making it the default.
Its snapshot capabilities are just so simple and well-designed. I dare say that it may be better than ZFS in some ways.
Nothing in this day and age is ... crud.. trying to think of the way to say it (forgot much of my English..)... I remember when we had assembly ( of course, we had WATFIVE, etc)... and BASIC (when I actually started).. we had no idea about how to format a damn HD (or floppy)... about 8 inch back the.. and a massive HD was about 12 meg
My first 2 PCs had NO HD.. first modem was 300bd :p
New format? ... yes, I am cautious... :p
