Well, I have not kept up on mp3/wav/<audio fil> portable players, so your input as to a Gentoo friendly device is welcome. A miniture video screen is not necessary, and keeping costs down is desired. Google for this said device leaves me with this scant choices:
Sandisk has the Sansa Clip + Cowon iAudio 10 Creative's Zen Touch 2 I definately need something simple; able to copy <audio> files from a gentoo system over to the device with ease. I thinking of a robust application (gui) that runs on my gentoo box for file format changes, then easy copy to the device, in folders, playlists, management etc etc. Support for many various audio file formats is a plus, either in the management (gui) api or on the device, natively. I do not want anything crippled by apple, Sony, Redmond...... Possibly a custom cover for a Rasberry PI or something commercial or <?> is fine. I also have a large collection of audio recordings I want to be able to put into folders on the device, that are not commercial. James
