Yes, it wasn't just one MP3 player that Samsung brought out at IFA. The second in the their "emotionally sensitive" range is the smaller Samsung YP-U4, aka. the Litmus.
It weighs in at just 27.5g, has a very reasonable battery life of 16 hours and comes in 2GB and 4GB versions. Unlike the Diamond, you won't have to wait until next month to get one. As for the price, though, that's still a mystery.
