Amazon's new Kindle is finally—finally—waterproof. The new Oasis (same name, better bod) has a 7-inch e-paper screen, up from 6-inches, as well as a larger battery, and the ability to play audiobooks from Audible blah blah blah blah blah. Here's what we care about: Its IPX8-rated water-resistant aluminum body. The only tradeoff for this defense is the missing headphone jack. Don't worry, though: The device's Bluetooth will pair with wireless headphones now, and Amazon is on-trend.
