Not as convenient as the guide, but you can access some other features this way. For example, you can list the top downloaded books for a genre.
I'll add the possibility to sign in on the mobile version this week: this way you'll be able to leave comments about a book, or get a customized list of recommended books.
I just realized that you have the RSS->enewspaper service. Could you add mobipocket format? It would be a plus to provide auto email service to kindle too...
