Gates noted that DRM "causes too much pain for legitimate buyers" and overall is not an effective solution. He went on to say that "DRM is not where it should be, but you won’t get me to say that there should be usage models and different payment models for usage. At the end of the day, incentive systems do make a difference, but we don’t have it right with incentives or interoperability."
There’s also an overall disillusionment with consumers in regards to DRM media files. Music files purchased on iTunes can't be used on Windows Media “PlaysForSure” devices like the SanDisk's Sansa players or Creative's Zen lineup. Even more shocking to the system is that PlaysForSure music files and services won't work with Microsoft's own Zune players. Instead, Zune users have to purchase their content from Zune Marketplace.
When it comes to music files, Bill Gates simply had this to say in summary; “People should just buy a CD and rip it. You are legal then.”
