Every once in a while something like this comes up that reminds me how incredible Apple can be at engineering, and how much attention they can give to the details, when they really try. It's so strange to contrast this with, say, the egregious regressions that so commonly happen in their OSes.
There's a trope that management always prioritizes new features over mitigating tech debt. I'm sure that happens on some teams, but without inside information it's a bit of a leap to assume that's what's responsible for this specific set of problems at this specific company.
I wonder why my Samsung Gear S3 has nothing like this. Its water proof and has speakers as well but there is no "you cant use your watch because its wet". Until now, I didnt even think about this might be an issue. The watch just... works. No matter if wet or not.
Must be a similar reason to why you can't use an iPhone/iPad/Macbook for about 10 minutes after the battery runs out. When you plug it in to power, it will refuse to boot until the battery is at least slightly charged. This is unlike, say, an Android or Windows machine which will allow you to use it immediately as soon as you plug it in.
I think Apple just simply does not care about user convenience.
It used to not be like this, back when I had an iPhone 4 it would boot immediately. But then it would die as soon as it got to the locksreen, halfway through me putting my passcode in, or as soon as I unlocked the phone.
Having to wait a little bit tops the frustration from getting your routine interrupted by the phone dying at random points. I usually waited a few minutes anyways to avoid the random shutdowns.
Water can create false touch inputs, this should be the case for most of not all capacitative touchscreens. In my experience the speaker still works well enough if wet and Siri weirdly also works but a person you call with the Apple Watch will have a hard time understanding you. How is calling on the Samsung watch with a clogged mic?
They're all recreations. Look up Foley if you want to be disappointed in almost everything you've heard on a TV show or movie. For example, elephants don't make loud thudding noises when they walk -- that's all made up.
