I just wanted to give special kudos to Sony for the new "Delete Book" option for the 505. I'm not in trouble with memory or anything. (Lots of books and still 70MB+ free.) when I finish a book I simply delete it right away. And, I simply load any new books of interest onto my Reader. This simplifies the pc connection process, as I don't have to search and delete books I've read. This lets my Reader serve as a collection of my current "to-read" list--I simply select any book on it and off I go. No more hassle getting rid of stuff I've read when I connect to the pc. I just keep adding new books, which is easy.
This may not seem like a huge thing, but it makes my usage of the Reader a lot cleaner and easier. I'm really glad Sony added this feature,
