Can someone please let me know if installing VoidMP3FM onto a NW-E00x device makes it 'truely' portable. By truely portable, i mean in the sense that the USB MP3 player can add & remove music on 'any' computer it is plugged into. From what I have read the software gets installed onto the flash device & then can be operated from within the device itself. Just trying to make sure I havent overlooked something & hopefully get rid of the dreaded mess of software that is, SonicStage. Thanks in advance.
