Excerpt: Overall, the MPIO-DMK is the perfect player for those on the go. We say this because the DMK is so tiny that you will hardly notice it on you. The DMK is perfect when working out both in the gym and on the street. This is the easiest mp3 player to use and anyone can learn its functions in a matter of minutes; it is an mp3 player for the rest of us so to speak. If you have hours to spend categorizing and storing albums of music on a hard drive, look somewhere else.
