Why don't you tell us how you really feel?
Meanwhile, I'm sitting here with a PC, moving and renaming files on the AK120II and AK240 without a single issue. Works perfectly fine in Windows... You know what? The more I think about it, the more it seems like the issue is with
OSX's lack of support for the MTP standard. Whoa, I just noticed that this fact has been discussed a zillion times on the AK240 and AK120II threads and in just about every review of the players.
But please, go ahead, design a web page exposing these horrible truths and let us all tremble as your mighty exposé chrushes the dishonest company of iRiver.
Be sure to post a link, I'm waiting.
