Apple has never been very happy with the prospect of fixing your iPod or iPhoneunder warranty just because you dropped it in the toilet. That’s why they’ve started cramming so many moisture sensors into the gadgets: the tiny stickers — which change color if they are exposed to an inordinate amount of moisture — give Apple an excuse to deny you service if things get too wet.
Apple’s rationale here is pretty sound. After all, if you trip and spill your iPhone into the drink, that’s pretty clearly not their responsibility. The problem is that those moisture sensors and their accuracy are both highly contentious: Apple’s fighting a lawsuit in which a California woman claims they are trigged erroneously by the humidity, and indeed, those who live in more humid climes have been complaining about false moisture positives for years.
With that in mind, it’s sort of distressing to see that the new MacBook Air uses a record amount of moisture sensors internally. In fact, by my count, there are 9 moisture sensors exposed in the image above alone… and there’s apparently even more hidden underneath connectors.
