I really like your idea of an ebook format wishlist!! In addition to transferring the title when it becomes available in ebook format, it would be great to have an email or something to let you know too. I'm not sure I would notice it appearing in my nook wishlist otherwise, my list is a bit long.
I also agree with your idea.....I think it would be great for the people that are in charge of making ebooks and whatnot to have a certain page where we could go and say that we want to see certain books come out in the ebook form because i do have a book i really want to read that is not in ebook form. It is "The Night Stalker the Life and Crimes of Richard Ramirez"
So I think it would be great to have a wishlist of books people would like to see come out in ebook form!
