Samsung's YP-Z5, their new ultra slim, shiny, flash-based music player looks quite slick with the black glossy surface with a shiny metal border, but it just loses its shine when placed next to the iPod Nano's signature metal rear. The YP-Z5 plays back MP3, WMA and OGG audio formats. The bundled earphones are excellent and the overall audio quality of the player itself is fabulous.
