Kudos to him for admitting he was wrong about ebooks though. He actually says: "This week, I set out to deflate the hype about Amazon's new Kindle e-book reader and to tell you why it will fail. But while researching this column, I became convinced of the opposite...."
So it's cool that he admitted that he was wrong. But why the Kindle changed is mind, rather than e-ink, is a bit off. But at least we have someone switching over to the e-book side.
