I'm not sure that I'm a fan of the pre-order pages, to be honest. I did it once before, and have since declined the offers to set one up. It puts you in one of two situations, neither of which are fun for me:
1. The book is done and ready to go, and you are just arbitrarily keeping it from readers. Which isn't as enjoyable as hitting "publish" and watching it go live 8 hours later.
2. The book is rushed to completion, and you force it out the door before it's done because of an agreed-upon date.
The third possibility, where you just happen to finish the book the night before the due date and it all goes perfectly, seems unlikely to me. And imagine the stress if you were cutting it that close!
There's the argument that you have a chance at bestseller lists with pre-order pages. Not sure if that's worth the strain. The reason I did this one is because I agreed to hold off publishing for two weeks in order to time it with the UK release date. In the past, I've annoyed overseas readers with a delay. I'm experimenting with annoying domestic readers this time.
