So yes, you can use any electronics under water if you have the PCBs and connectors nano-coated (is that the right way to say that???). Motorola is already starting to do that with some of their devices. The benefit to having the nano-coat applied to the device is that it's easier to clean, it's weatherproof, and it can even survive being dunked into liquid. I saw a demo done on a piece of tissue paper and immediately, I was like "whoa, that would be VERY useful." I'll see if Liquipel can help me. A weather proof iPad and smart cover would pretty much make the device awesome for medical and outdoor use even in heavy weather.
