Different energy. Bus driver has to deal with many potentially grumpy people in many potentially unsafe areas. Not an easy job.
A doctor that is specifically specializing in a field where he has to get to know and take care of children as they die in a potentially painful way, has a much different challenge. Less for safety or aggressive people (though maybe parents could be I guess) but more in being the one to watch as the hope fades for each individual child in their last days.
I wouldn’t love the bus driving job. I don’t think I could do the pediatric oncology one for more than like, one patient ever. I’d be depressed forever.
You wouldn’t want to wear a dive watch if you never dive, so why put that feature set on everything? Probably similar thoughts for a lot of these models.
That said, you are correct that they should streamline a little. It’s a ton of nonsense and very frustrating to hide features that are clearly being calculated (HRV) but hidden because you didn’t buy the right model.
One glaring omission for me is the lack of database options in the app store. They have a TINY bit of hard drive dedicated for a third party app. I used to own a Samsung and wrote an app for my gym workouts. It was great, but I like Garmin watches better. But even if I use the available key value pair database on Garmin, it only gives me space for maybe 100 sets before I am out of memory. Useless if you want to track any kind of history for multiple workouts. Same for the disc golf app I made for Samsung. I could technically save enough to play, but my old app has room to let me know all my previous scores per hole at each place I was, etc.
This isn’t a huge amount of space needed for these things. A few MB. But it’s walled away for some random reason. Really limits developers from making good stuff.
