personally, i'd rather not use it. more than likely you can listen, or play. i like to play and listen to music at the same time. i'd rather get a junk computer for free or really cheap, network it, plug it into my stereo, and stream from my library of music. it's like a cheap "media center pc"
in college we did that. we'd be downstairs getting drunk playing GTA and other such games, streaming music wirelessly with a massive playlist (or a short one). it was a room mates from home that nobody was using (over 5 year old gateway). it needed a cd rom cuz it didnt work properly and i put xp on it, and a wireless card that i already had. worked great
