[Trisquel-users] Digital audio player and free software

[alonivtsan]

Is there a digital audio player that is sold with free software such as  
Rockbox or one which enables installing Rockbox without voiding the warranty?  
I currently use a Rockboxed iPod Video (fifth generation iPod) which mostly  
runs free software (the original firmware is used for charging purposes), but  
I would prefer something which is more standard (i.e. includes a mini or  
micro USB connection, supports removable storage such as microSD, includes a  
radio, has a built-in speaker, can be charged via the computer and used at  
the same time etc). Thanks for your help.
