I've been reading a lot of messages on this list about potential and actual corruption of a zpool due to cache flush problems and whatnot, and I find myself amazed.
You should not be amazed. People only take their radio in for repair when it breaks. Therefore, the radio repair man only experiences broken radios. Meanwhile, millions of radios continue to work without fail. It is the same on discussion lists and forums.
I just wonder how a zpool compares with a good old filesystem when it comes to filesystem errors. It seems several of the members of this list have encountered problems where they had to boot a live CD to get their pool back, whereas a normal filesystem won't give this problem. The old-time filesystem might have corrupted data, but it still gets up.
Most "old-time filesystems" are tremendously smaller than today's zfs storage pools, and they might even be on just one disk. Regardless, only someone with severely failing memory might think that "old-time filesystems" are somehow less failure prone than a zfs storage pool. The "good old days" does not apply to filesystems.
