The anti-DRM argument in this paper is incorrect.

Such constrainst on behavior might include: … file incompatibility that makes it impossible for users to transfer their iTMS songs to any portable device except the iPod…

Burn a CD with a playlist. Even burn an MP3 CD. Regular CDs can play it. CD Players that support MP3 CD can play the MP3 CDs. You can even rip the CD into the app that ships with whatever other player you want to use. Resulting sound quality is still better than one typically gets downloading MP3s off the file sharing networks.

Is it the most convenient way to move music? No. But it’s not pernicious anti-competitive lock-in. The overall model makes for a nice place for the iPod and licensed knock-offs (HP), but does not exclude other devices. That subtlety seems to be lost on Ernie and other anti-DRM crusaders.

Just picking a nit…
