Source?
Basically I was more interested with the DRM side of the Zune with the wireless Zune to Zune copying and the subscription side of the whole Zune thing.
I kept coming up with articles in my "DRM on the Zune" search in Google and Yahoo! to do more with the fact that the DRM on the Zune is very similiar to the "DRM" on the Sony laptops a few years back.
When you see what the Zune can do it stands to reason that there would have to be some substancial control on the behalf of Microsoft. You are renting music from them and therefore Microsoft will want to know what you are listen to and copying other Zune for marketing purposes and copyright (yay DRM).
Personally it doesn't surprise me if we see another "DRM" legal battle within the next few months to do with the Zune because after all who came to Sony's aid with the rootkit debarkle and who doesn't have a great track record when it comes to ethical business practice? Microsoft
