I really hate agreeing with J S Wolfe but this time I just gotta.
I have a Paperwhite 2 and I think it's an excellent device and $10 off makes it even better. But since the newer model, which has an improved screen, is only $10 more, That makes more sense.
If someone is really eager to save $10 there's certainly nothing wrong with the Paperwhite 2, though.
