* Siri - no thanks
* Far field microphones - no thanks
* Faster performance - unnecessary for me (I watch TV, movies and YouTube - it's never not smooth)
* Home theatre with homepods - I already have Sonos surround
* Even smarter home hub - I have a non-Apple smart home
* Facetime, Fitness+, Apple TV app - just not for me
The one thing I feel like I'm missing (and would be missing even if I upgraded) is audio passthrough, but DD 5.1 is _fine_.
