Had a chance to listen and use a Zen Micro today. Compared to the pod it wasnt very resposive and seemed to lack when changing tracks while it was instant on the mini. Connected a pair of computer speakers to both and listened to the same track (Zepplin - When the levee breaks). I wasnt expecting the Pod to be as good as I didnt have my dock with me, but to be honest it sounde better than the micro. Still to listen to the Sony HD5 which obviously has 4 times the capacity but I have still not heard anything better than mine and with 18 hours battery I can't complain.
