My friend and former Macworld colleague Heather Kelly tried the new waterproof Kindle Oasis in the bath. It didn’t go great:
Water, it turns out, triggers the Oasis touchscreen. One small splash can turn the page, change the font size, exit the book or do anything else a rogue hand might. In my tests, it didn’t take more than one fat droplet to activate the 7-inch touchscreen.
So, yeah: the Oasis’s waterproofing is fine if you don’t want it to get damaged when it gets wet, but don’t expect to get a ton of use out of it in a water-filled environment.
