I have an OLD archos av420... it has to be like 4+ years old and all I have to do is plug it in, and it is recognized as a storage device. I have an even older creative nomad (7 years) that needs drivers to be installed, and then it works.

I don't know about those horrible ipods, but most mp3 players should be recognized as a storage device, requiring no software to use them at all. All you have to do is drag and drop music in Windows Explorer.
