I know I will definitely be downloading this to my Nook first thing on the 26th.
I bought the nookbook from B&N today. Don't start reading it just yet. There are some major issues with the CSS that I am working on fixing. For example, the fonts are a mess and there is no italic showing. The code in the XML for italics is there, but the CSS is not right for displaying it. I'll can post the CSS once I have it fixed.
If I am not mistaken, I believe there is a way to swap out an encrypted file for one not encrypted. I will see if I can find out how to do this in case you do not have the DRM removed.
It also turns out that S&S left out the bold-italic font and bold-italic is used. I've found the fonts needed and have replaced the ones S&S used. This one is one heck of a mess and it will be fixed.
