Google for "macbook fire" and look at Google images for some other unlucky ones.
Yes you are lucky because you spilled from the top which it's obviously at least slightly better at handling. If the base gets even slightly wet, boom.
"No hyperbole, the design is simply dangerous."
"If the base gets even slightly wet, boom."
Right. No hyperbole.
But what you said before is that the notebook in your story was sitting in a puddle of water, 10ml seeped in, and then when you turned it over, you heard "crackling, smoke, etc."
An electrical short, yes. But not an explosion.
Sure, if the cathode comes into contact with water, that's a big problem. But the battery itself is well sealed. Your criticism seems to be half baked here:
When you say their design is "dangerous" that sounds like you're saying its dangerous to the user. That it will cause injury.
But your real criticism is that you can't "isolate the power." That is, the sealed case makes the battery dangerous to the machine: You turned the machine over, and logic boards, still hot with power, shorted when the water hit them.
But the implication that it's dangerous to consumers just doesn't make sense: Removable or not, if the lithium comes into contact with water, you've got a problem.
Moreover, I think it's disingenuous when you pull the "I'm an expert" card and then provide editorial analysis: Of course if you google you'll see the bad "unlucky" macbooks that got wet. The people who are "lucky" do not post pictures of a pristine, dried-out computer. There's a selection bias there.
