iTunes Plus and DRM Free.... I haven't quite grasped it yet...

[SKYLANE]

I went to mp3 format since my car audio would only play mp3, not AAC. I knew there would be degradation in the transfer from AAC to mp3, but for the car I did not care. Some of the AAC files that I do listen to on higher quality system I did leave in iTunes folder.

So, if the new songs are DRM free, what protects from trading AAC files all over the place?

Does the limit of 5 authorized computers go away too?
