We get it, some people don't want to charge a watch even though they have to regularly charge their phone, headphones, laptop and maybe car. Such a weird flex that a watch lasts an extra few days, who cares?! Charge it while you shower and you're good to go
The fact that these are your top 3 reasons to consider Apple Watch as the only brand to own speaks volumes about why monopolists shouldn't be allowed to keep APIs private indefinitely, the way Apple has with every API the Watch uses. I'm pretty sure every API that smartwatches have access to on iOS were introduced before the Apple Watch was a product. In other words, Apple arrested the progress of all other smartwatches for everyone on the iOS platform in 2015 so that they (and their fans) can smugly tout all these exclusives. (I'd add to your list the 'make my phone beep' feature, which is the main reason my whole family owns Apple Watches.)
I can see the appeal of smart-watches for some things, but I'm too attached to my (small) watch collection to ever consider buying one.
