So, here's the deal. I have no experience with this exact case, however, I do have a hard zip case from the same company that I bought clear back around the time of the Kindle Touch model, and that thing has performed VERY well. It's nicely crush resistant, and mine will actually hold two Kindles, even if it's not exactly designed to do so.
I'm thinking this iPad Air version might work similarly... There does appear to be an inner pocket that could potentially hold a Paperwhite. The catch is, there's no built in padding to separate the two.
