I find your assessment of the Linux filesystem situation to be inaccurately, and surprisingly, negative. "Stuck with" implies little potential for change, when there are several filesystems which are being developed at a swift pace, solving tough problems with vigor and ingenuity. btrfs is coming along just fine. I can't think of any place with more filesystem development going on than Linux.
