Also if you need to feel like reading a book, the transition is easier with the case. it makes me feel that i have something in the hand. Still after two weeks using my Cybook, i am feeling more and more confortable without the cover, in subway or at home.
If the battery is only used when turning a page, there is no point in shutting down the Cybook after reading.
Personnaly i just put a nice pic and let it like that...
