Lol, I guess I'm not surprised. I wonder if more copies will leak out at some point...
I think it is a brilliant move on Amazon's part. The HP franchise made them oodles of money (and still will for years and years), that it just seemed like an item that they should have. I don't think they're going to publish copies and copies of the book just to make more money (although I wouldn't be completely surprised if they did, just disappointed), but if they have a corporate office or something, they should put it on display or something. Plus the $4 million they paid for it goes to charity, how cool is that?
Yeah, I don't think JKR did it for money, and Amazon probably doesn't need more money from extra copies. But I guess I wasn't quite sure if JKR's idea is to only have 7 existing copies, or 7 original handwritten copies and have many copies of just the book's content or scanned versions of the book. I mean there's gotta be lots of people willing to transcribe it, and then everyone could read it and get a kind of postcard version of it.

Speculation...

It's so cool you found this, though. I sent it out to one of my school's mailing lists and everyone's pretty excited to see it.
