The Rio PMP300 Player is about the size of a cassette tape case and very light.
Installation is very easy and a battery is even included.
In a test version of the software bundle, MusicMatch Jukebox is included to provide an all in one solution for encoding, ripping and playing songs. The Rio Manager is very easy to use and has a slick interface. It can play MP3 files and easily create Playlists that you can download to your Rio unit. An important component is the Internal Memory window, where you download the songs into the unit, and it displays how much memory is available, name of the songs, size, date etc. Everything is controlled by five different buttons, Open, Download, Refresh, Delete and Initialize.
