Over the years, Apple has increasingly put more and more moisture sensors inside their laptops: little stickers that tell Apple Geniuses when a device has been exposed to liquid, useful for denying you warranty coverage for the iPhone you dropped in the toilet, or the MacBook you spilled a beer on top of.
No surprise, then, that the Retina MacBook Pro has moisture sensors inside the chassis, but what is more surprising is how many it has: ten in total, two more than the MacBook Pro and MacBook Air.
I suppose it makes sense: the Retina MacBook Pro is an expensive piece of kit, and Apple doesn’t want to have to replace any more than they need to. You may want to watch out for your drool hitting the keyboard when you first check out that Retina display, though: Apple’s not going to fix that.
