I dont know if this has been posted before but i recently was using iChat and listening to a song on iTunes...A buddy came on from europe who owns a 12" PB and we decided to do a voice chat to see how well it worked. The quality was awesome but what impressed me more was that my song in iTunes faded out as the voice chat started! i didnt notice it until we finished the chat and my music came right back on! wow..on my PC i would have gotten horrible interference if i didn't turn off my winamp.
