Bah, I'll pass... If it's only shipping on a 128MB device, then the audio on there is NOT CD quality, and must be some compressed audio format. Given the push for DRM by the major music labels, the data will probably also not be in a format I desire. (192kbps VBR MP3, LAME encoder thankyouverymuch)...
This is also of concern to me. I've gotten to the point where I'll only rip .wav files if possible, since I cannot stand "wobbling" cymbals. This limits my collection possibilities, but that is fine.
This is apparently mp3, too, and not a non-lossy format like I hoped. An album of around twelve tracks averages 500 MB in size when encoded at 1411 kbps, and this is 29 songs.
