On one hand I think this is a really cool idea, and I am glad to see that all the money goes to charity. On the other hand it makes me sad that the average reader (me), who does not have 4 million to spend on a book, will not be able to read "The Tales of Beedle the Bard." I really hope she chooses to publish this in a more affordable form, because while I appreciate the uniqueness of the hand written books I care more about the content contained therein.
Don't get me wrong, I like J. K. Rowling and wish her nothing but the best. I just selfishly want to read the story.
