I'll look at the Aura when it comes out, since my Aura HD bit the bullet. Sad thing is though, I'm not too enthusiastic about eInk at the moment because the only one that I've owned that stood up to day-to-day use was the Kobo Touch. So I'm thinking that I should wait until the flexible screens (i.e. the ones with a plastic substraight) are available.

Since I do a lot of reading outdoors, that means it's back to printed books.
