I'm going to try this one:

(In a few other listings, this case is said to have auto-wake and sleep.)
I've also considered this one:

However, it seems the Touch will also fit the case, and that reader is both bigger and fatter than the Paperwhite. When you look closely at the pictures, especially nr. 6 in the list, you can actually see folds in the case's side. I think this case was originally designed for the Touch, and the PW just happens to somewhat fit.
Also, I like the lid of the first case better, as the hinge runs along the entire length, but I don't know how I will like the pebble texture.
I don't know if I'll even like to hold the Kindle with a case around it. I also use my tablet and smartphone bare, and they're in a sleeve of impact foam and a leather pouch respectivly, when not in use. For my Kindle, I have a smaller version of the sleeve I use for my tablet.
Ah well, if I don't like this case (or none at all while reading), I'll just sell it again.
(BTW... That kindle seems photoshopped into the second case. The corners should be visible I think, or the case is way bigger than the kindle itself.)
I also like the cheap form fitting one, but hate that it doesn't have a magnetic lock. (This is also the first case ever that I like in brown, or in anything else than black, for that matter.) If the case opens a bit inside a bag, the Kindle will turn on and drain your battery. But, I really don't like the one with the lock, and I find the Amazon case ridiculously expensive at almost 30% of the Kindle itself.
