I'm also underwhelmed by this release. I thought I read that the library software was going to be updated, not the bookstore. The user experience with the ebook library is sorely lacking. You are unable to do the most basic tasks that most organizing software allows. They can do whatever they wish to the bookstore and I probably will only go there for free stuff. I would possibly purchase a few books if the library was more like itunes, as I would be using the software daily instead of every few weeks. Calibre [libprs500] rules for now.
