My significant otter is a fastidious painter and graphic artist who carries her approach into the minimalism of her decor, esp. when it comes to water corset filigree. I tend not to have several brands of shampoo or soap survive the constant winnowing process, let alone foreign devices normally seen in other parts of the house. I can't imagine her brooking an old e-reader installed in the room permanently.

For those who don't have such issues and are looking to grandfather their hoary incontinent last-gen readers, I can recommend a
splash-proof Octovo case for the K3. It seems to be $9.99 at present, but when I bought mine, it actually came to $0.01 during an Amazon sale and you might find one at a cheaper price.
