Does more e-book competition lead to more DRM?

On PaidContent, Bill Rosenblatt looks at whether we can ever expect a universal format for e-books, equivalent to “MP3” for audio. He doesn’t think so. For one thing, he points out that MP3s aren’t actually used all that much in digital music sales.

He also points out something interesting about DRM and consumer lock-in. The obvious feature that gets blamed for lock-in is DRM, but it’s not the only way.
