you can get music but it took them long enough and only happen because if not the courts would of crack down on them.
Movies nope Apple products only.
You clearly don't understand what happened regarding the music and DRM. You really need to do your research. Here's a hint: The music industry required Apple to put DRM in to be able to sell their music. Apple didn't want DRMed music and finally convinced the music industry to give it up.
DRM doesn't do anything good for retailers of digital download content as it hinders them from competing against physical discs and other traditional means. It's only the producers of content that want DRM and they are the ones that stipulate in contract with retailers like Apple, Hulu, and Netflix that they must provide some sort of DRM to be able to sell the content.
