I also just received the gift basket and thought it was a nice touch (and I also got the Halloween stories instead of Christmas ones).
I noticed last night that the clip-on light that came with the basket appears to be capable of using a power cord instead of batteries (but no power cord incuded). It's got stuff printed that looks "power" related and it definitely has an input.
ETA: I purchased a book through the Sony bookstore yesterday hoping to at least get an option of what format and I did not. And as it happened, it was the original Sony format, not ePub. I'm o.k. with this since I also understand I'll be able to redownload the book in ePub when the site is converted by year-end.
