Yeah, I like mine, but there is plenty of weirdness.
- I get congratulated for standing up all day, even though I'm mostly sitting down
- The later models have the screen on all the time, but I keep mine off to save power. It doesn't always wake when I look.
- Find my devices is completely ****ing useless and rarely can see the devices. It's great on the phone and Mac.
- I barely pay using mine due to the number of times I'd get to the front of a drive thru, try and pay, only to be told "card updating". However far away from me you live, you'll have heard the cursing.
- No idea about Siri, it's shit on every device.
There's plenty more. They're off the top of my head.
