Anyone seen the ad where a "Sony Xperia Tablet Z" is running with the display on inside a fish tank? Next they spill something on the tablet then clean it under the tap then toss it into a gym bag with out bothering to put the tablet in a case. People at Apple need to see this Sony ad. Apple installs water sensors in their products so they can prove water damage and avoid in-warenty repair costs. Maybe they should follow Sony's lead and use the money on waterproofing and then have no need for the water sensors.
