So far, I'm not that happy with the newest firmware. It seems to be running more slowly than .17, and it doesn't support subfolders - by that I mean I cannot get covers on epubs in sub folders. For example, I used to have folders set up like this on the micro sd: "A Christie> Miss Marple> <epub name>. That didn't give me a cover, but just dragging and dropping onto the micro sd card seems to. I hate that as I had my files nicely organinzed by genre.
