It's one thing to have a look at a new user interface in pictures, but watching someone navigate it on video is just so much more meaningful and soul stirring. Cowon's S9 isn't due out in South Korea for another five days or so, but it looks like someone with a video camera and a YouTube account completely missed the memo. For a likely limited time, the video just past the break shows off five minutes of admittedly responsive UI interaction, complete with the ability to alter the equalizer preset from the Now Playing screen (what a concept!). Be warned, though -- the first album to pop up is Mamma Mia!. Terrifying, we know.
