The ebook readers that I have used are all somewhat flimsy. I am looking for a device I can take along when camping this summer, without having to fear too much for breaking it along the way. Not talking about dropping my backpack in a crevasse, but something that at least withstands the pressure in my crowded backpack. I can of course pack it at the side, but then it is more like to get busted when I bump the backpack into a tree.
Something like the a Panasonic Tough-pad, without the price and shortened battery life of a non e-ink display.
I have read What are my options for reading an ebook in the bathtub?, and waterproofing is one nice thing, but putting things in a zip-loc bag doesn't make the reader more robust. If I cannot find nothing I probably take an old Kindle, packed with the face against a matching piece of aluminum sheet and hope that suffices.
