I've been using a combination of ReiserFS and ext3 on my desktop, and
ext3 on my laptop, for over a year now. The only problems I had were
due to the kernels between 2.3.99 and 2.4.4 not dealing with VIA686
chipsets properly. Other than that, I've had 5 or 6 unintended
shutdowns for various reasons and never had data loss.
Can't speak for OS X since I don't have any hardware that's capable of
running it, but IMHO there's no reason not to use a journaling
filesystem on your Linux machines.
Another performance tip for Linux machines: Mount your filesystems with
the "noatime" option. Most of the time, you don't need atime; you're
interested in mtime if you're interested in file times. If you're not
updating atime, you cut down the number of disk writes by about 5%,
which can be significant on heavily-accessed filesystems.
