Keep in mind that you are not representative of each and every linux use case in the world.

Short answer: No, it's still considered experimental.
Long answer: Nobody is going to magically stick a label on the btrfs code and say "yes, this is now stable and bug-free". Different people have different concepts of stability: a home user who wants to keep their ripped CDs on it will have a different requirement for stability than a large financial institution running their trading system on it. If you are concerned about stability in commercial production use, you should test btrfs on a testbed system under production workloads to see if it will do what you want of it. In any case, you should join the mailing list (and hang out in IRC) and read through problem reports and follow them to their conclusion to give yourself a good idea of the types of issues that come up, and the degree to which they can be dealt with. Whatever you do, we recommend keeping good, tested, off-system (and off-site) backups.
Pragmatic answer: (2012-12-19) Many of the developers and testers run btrfs as their primary filesystem for day-to-day usage, or with various forms of "real" data. With reliable hardware and up-to-date kernels, we see very few unrecoverable problems showing up. As always, keep backups, test them, and be prepared to use them.
Early Btrfs code? It was prone to error and bugs and corruption-- most of those, if not all of those, have been worked out now if you are using a recent kernel (seriously, dont use BTRFS on Ubuntu and then complain about it... try it on Arch or Gentoo or Fedora--somewhere where you have a RECENT kernel, and then see if its stable and good for your uses). I've had one filesystem corruption issue on a recent kernel and that was on Fedora 18 Beta because the laptop's battery died during the initial update. I could've tried to fix it with btrfsck, but since I had JUST Installed it i figured "Screw it" and just redid the install. After that it worked perfectly fine.

If you have two disks, this is kinda useless anyways;
Just put the operating system on your SSD,
then put all your movies and music on the HDD.
Should they buy 8TB in SSD? Don't think so.
Everyone isn't just using their computers to play games and watch porn.

Also I read that Windows has a different way of doing something like that where commonly used files that do not reside on the SSD have their preferences and indexes stored on the SSD instead to speed up retrieval...or something along those lines.
