Do you think the authors are receiving info from Apple now to prepare their books (after signing a Non-Disclosure Agreement of course), or will they not be able to do anything for another month until they get their hands on one at launch?
It's cool to wonder if any NDA authors currently exist or not. And just imagine: if they do, they would be privy to any 'One More Thing' surprises not yet revealed, while the rest of us can only wait!
