What if Harry Potter 5 Was an E-Book?

hakkikt sent a link to a highly speculative what if story on Harry Potter 5 as an E-Book. The suggestions are pretty extreme- going so far as to saying that this one book could change the fates of the publishing industry, book stores, and could even make E-Books more then a pipe dream. Personally I'd love to see it available digitally, but I still want a real hardcover copy, and I can't imagine hundreds of thousands of kids staying up late at night with laptops under their covers instead of the far more traditional book & flashlight. Food for thought, but I can't really take it seriously.
