“Reduce interruptions” is REALLY nice, I just leave it on permanently so whenever my watch taps me, I know it’s something I need to look at and it’s spot on 99% of the time.
It’s the only feature that has legitimately surprised me at how good it is, but I wouldn’t buy a new phone for it. Everything else is whatever, the safari summary is nice when someone sends me an huge article and I want to know if it’s worth reading, but again, not worth buying a new phone/computer for.
The only reason I’d suggest an upgrade is if you’re still on an Intel machine. Even a cheap 400 dollar M1 MacBook from Walmart will run circles around what you have now, that’s absolutely worth an upgrade.
