I agree on the delete option! I would love to be able to delete books when I am done with them. If I like the book, I'll keep it on, and that reminds me to look for other books by the same author. But if I don't care for it, I'd just delete it. Also along with that, a way to move, or copy books would be great. (I just discovered that option today when I downloaded LBook firmware. I went through a bunch of books I read recently, and copied the ones I liked to the main memory, then deleted them. And I deleted the ones I didn't care for. Now I will be able to easily find more stories by the authors I enjoyed.) I would prefer having Astak firmware, but I figured I'd try out the LBook and see what it's like.
