"This design allows the iPod to switch between music and video mode by way of a sliding mechanism. In the "closed" mode, the player appears as current iPods. In video mode, the entire front face of the iPod slides away to reveal the full sized screen underneath. Screen is protected from impact and scratching in music mode."
