If you couldn't tell from the shots yesterday, the upcoming Samsung YP-K3 player is really thin. Arguably the thinnest player from Samsung, if not anyone, that we've seen.
To refresh, it's got a 1.8-inch OLED display, FM Tuner, up to 4GB of storage and MP3/WMA/OGG playback. We bet you could probably stack three of these up against one Zune.
