well Let's TALK iPhone is obvs about the new Assistant feature no one will ever use, just like the facetime camera. a feature u use once and never again lol
it just depends on what assistant can do. if i can tell it "set alarm for 8:30am" and it does it faster and easier than standard ways I'll be all about it.
"send text to xxxx, say blablabla" would be awesome when driving, same with searching for places and getting directions
I would love if it is aware of your activities and you could program it to make sure you got out of bed, yell at you when you're about to eat junk, motivate you when you're feeling down, give logical advice, etc..
