Yeah, I wish there was some advancements made when it came to trying to create swappable battery devices that retain water proofing.
If nothing else, regulations like the one described in here will do just that. So far the tech giants haven't had any incentive to design sleek, waterproof devices with replaceable batteries. But you've gotta believe that if they're required to have replaceable batteries, they're not going to say "OK, back to chonky non-waterproof devices for us!". They're going to spend some of their R&D budgets to innovate ways that makes it more realistic to do all three.
I'd probably pay the $50/year if it included an API key so I could read with any client I wanted to.
