I also had some experiences with jffs2 on a PDA a few years ago (iPaq
with familiar linux), but no good ones. It was slow, and regularly got
corrupted beyond repair. I think it has improved in the mean time, but
of what I have heard so far, it is still slow. Probably too slow for my
48MHz PowerPC. I haven't tested it yet myself, though.
