I think the piece misses a couple key points:
1. "Physical" ownership of the file - The song file can be downloaded to any computer, including your Android phone. This gives a sense of ownership of the digital file (hopefully Amazon won't change it's policy later). iTunes is much more restrictive, and I'm sure Apple's cloud music service would be just as restrictive.
2. Android integration - IMHO, there isn't a nice music player for the Android OS yet that can sync playlists and such across your devices, but this may be it.
