What I've never understood is why all this waterproofing effort is going into making perfectly sealed little boxes when I imagine that a factory applied conformal coating would do a similar job. It seems like they're focused on making the box the electronics are in water proof instead of making the electronics themselves waterproof. Sure, the screen might be a bit harder and you'd need to pay special attention to any connector, maybe re-applying the coating if you remove a connector, but I just don't get it. Does conformal coating not work as well as I imagine it does? Is it too expensive to apply? Does it have some kind of heat dissipation drawback I'm not aware of?
To me it looks like water proofing is being used as an excuse to add built-in obsolescence to products, since I imagine that conformal coating would do the job better. What am I missing?
This is about replacing, and thus having access to, the battery and it's terminals. Water is a conductor. I imagine shorting the battery terminals with water will have disastrous consequences, regardless of if the RAM is encased in epoxy.
