For users of the harddisk/mp3 player/recorder Archos series there is an great update.
From the website http://rockbox.haxx.se/
Rockbox is an Open Source replacement firmware for the Archos Jukebox 5000, 6000, Studio, Recorder, FM Recorder and Recorder V2 MP3 players.
Rockbox is a complete rewrite and uses no fragments of the original firmware. It boasts numerous features while remaining easy to use.
Installing Rockbox does not harm your Archos, it works the same way you upgrade your ordinary Archos firmware.
Greatest thing it did for me was removing the background noise and putting CD-playlists in their original order again.
But there is no auto shut-off after playing.
