Ext2 would be better on flash media, since it does not have to
write to the journal.  And you can use the "-o noatime" option
on "mount" to keep it from writing file access info to the
inodes every time someone reads a file.

You might also want to create RAM disks for /tmp and maybe
even /var.  This will require a startup script, but it's pretty
easy.  You might want to keep a skeleton /var somewhere (like
/var.tar.gz) and create the RAM disk, mount it on /var, and
then populate it.

This solution is so good, you can cook with it.  :-)
