yes, but it's not a compelling reason.

it still won't automatically save your opened staroffice documents.  it'll
help with fscking, but ext2 is pretty robust, and i've never really heard of
someone losing a partition because of a power outtage.

i think a big factor for small folk like us is the "coolness" factor of
having a journaling fs.

right.  and for the record, there's actually a few more jounaling fs which
are being made ready for linux.  reiserfs is only the first one that made
it.  there's xfs (sgi) and something that ibm has, which i can't remember
the name for.
