Barnes and Noble joining the battle?

CrunchGear has a story on Barnes and Noble's thoughts on their own ebook reader, and analyzes the business model for reader publishing:

Sony has tried to enter this space with multiple partners for years and while I agree that their products are fine if you’re a big old pirate, I doubt many of us have PDF versions of the latest bestseller lying around. Just as iTunes changed the way the average consumer gets music onto their music player, the Kindle changes the way people interact with ereaders. Whereas the old music/book paradigm was, essentially:

1. Find a service that isn’t full of spyware
2. Search for songs/books of dubious quality
3. Worry the police will arrest your unborn babies
4. Download music/book for free
5. Install drivers
6. Reinstall Windows
7. Plug in MP3 player/reader
8. Drag music to player/reader
9. Eject player
10. Discover the music is ten minutes of a twenty second loop of Gwen Stefani singing about Harajuku Girls/Discover that the book is written in German
11. Repeat

The iTunes/Kindle paradigm is:
1. Buy device
2. Buy music, maybe rip a CD, download a book, whatever! Drink a nice glass of brandy, maybe?
3. Play music/Read book
4. Repeat

Which process do you think is more lucrative?
