I suspect the large flexible screen is intended to give the feeling of reading a magazine. Just a guess.
I know that lack of lighting has been a sore point for a lot of people but it's not an issue for me. I have a good back lit screen on my Sony Clie and I find that I get eye strain from reading on it for a long period of time. I wouldn't want to turn it on and compromise battery life anyway so I'm happy without it.
Glad to see they're listening to their customers though.
