One of my favorite websites, Gizmodo, has a great piece up about e-book interoperability. As they point out, what Steve Jobs meant when he said “open” isn’t exactly what you and I might think of as open. The short story is that iBooks books will only work on the iPad (and I’m guessing the iPhone and Macs, at least eventually), just as Kindle books only work on the Kindle. That certainly isn’t my idea of open. And it’s not great for publishing, either, when people can’t take the books they think they’ve bought with them. It’s not the expectation, and I fear it encourages piracy. What do you think?
