I've been using Sony MD, then HiMD, and am between players. I thought to make the leap across to MP3 etc., but am frustrated by the limited number of players that will work with my Mac. I've rejected iPod and Archos, it's a personal issue I know, but I don't consider 10-15 hours of (non removeable) battery life to be truly portable. So, my question is: has anyone had any success with the Sony NW HD5 using, for example, Virtual PC? Or any news on the software for the HD5 replacement? And if it all works out, which is better, Atrac or MP3?
