Still, an obvious improvement. I see it as a good candidate to replace JFFS2 on CompactFlash. That one is becoming painfully slow with nowadays' smallest devices (around 64..128 MB). But since it considerably reduces the number of writes, and it can transparently compress, it's still worth using it in some environments.
