I’m okay with a thicker phone but I’d be much happier with a new Mini - MagSafe, thick or whatever. The next phone possibly be the last phone I buy before I leap to an Apple Vision Air.
I have to say, I’ve never found the top of the phone “heavy”, even when I had a gimbal. Started with an 8GB iPhone, then a 3GS, 5, 7, 11. Had car holders (first bouncing on windscreen and then clipped to an air vent) so I can see why MagSafe is cool - but it’s not essential. It’s just more convenient.
I sometimes think we all suffer from this pick-and-choose-itis, as if there’s obviously some magical combination to this piece and that piece and a quick juggle of compromises, to get to a phone people can afford and use for many, many years. I still have a working original iPhone in its box, and the 7 is in a drawer along with the wife’s 5s in case our 11s fail (so far, not). I think the choices they’ve made have overall been good but also I trust them not to obliterate MagSafe without a plan. They want you to be satisfied enough that your current phone will never just be tossed.
