Apple has applied for a patent on a consumer abuse detection system? No, it isn’t a system to protect you from their prices and products, it is a system that spies on you to see if you are abusing your Apple product. No, really.
Apple already includes liquid submersion indicators in its MacBook Pros, iPhones and iPods. They irreversibly change color once they come in contact with a liquid, thereby offering the company's retail store staff and authorized repair specialists an easy way to determine if a customer caused damage to their product with liquids -- incidents that aren't covered under Apple's standard warranties. Rather than the physical indicator, the new system would save information of damage digitally into memory.
