In all seriousness, I'm looking for a light, light mp3 player with a decent amount of storage - at least 20gb. What is the advantage of paying for the HD5 over getting the HD1 with the upgrade to play mp3s. The HD1 is the lightest 20gb player I can find (please correct me) and the other one that comes close is the archos gmini which has suspect battery time. Only benefit I can see if replacable battery for the HD5, but I don't think that account for the price difference. Let me know your thoughts, especially those with both HD1 and HD5. (also the spin feature on the HD5 is of no value for me) Thanks.
