It's an interesting phenomenon, but not the kind of trend I want to see. Kottke says: "In the end, people don't buy content or plots, they buy physical or digital pieces of media for use on specific devices and within certain contexts." I disagree: people DO buy content. If I buy a book, I'm buying it for the story; the format is entirely secondary, regardless of my personal preferences. Giving a book a bad rating because you can't read it on your Kindle or whatever? That's just bullshit whatever way you cut it.
