I have an SE2, and use it with both hands, even if I have to stop and put things down, but don't normally use it actually on the run like that. I simply don't have a clamouring need for a phone I can use in one hand.Of course, people will buy what they like and enjoy using, and I'm not against it.
However, it is difficult for me to understand how 6.1" smartphones are so popular, because I've tried to use the XR or the iPhone 11 with one hand, and it slips from my hand and falls to the Apple Store table. And reaching to control center with my thumb is impossible (it was a bit difficult on 5.8" iPhones, but it is impossible with a 6.1" iPhone).
What leads me to think, do people actually leave everything on the ground (bags, books, etc) and stop everything they're doing, to use their smartphone with both hands simultaneously??? I personally find that a waste of time, but for each their own. I need to use my smartphone with one hand to be able to keep doing things in my life while I answer a text or a chat message or even this post on MacRumors while I travel on the bus hanging with one hand to the bus bars.
And no, my hands aren't tiny. They are average, with long thin fingers.
I absolutely love it that Apple made a mini so that people had the choice, and I hope they keep making it, even if it isn't a huge seller, and also hope they make a mini pro, for the same reason, but I will never buy either.
For me the size criteria is the biggest phone that will easily and comfortably fit in my pocket. So if anything, I'd like a bigger phone, but the 12 Pro Max is way out of budget for what I could justify to spend on a phone.
I type on my phone with one hand while the other hand holds the phone, but I've noticed that most people, especially younger people, type with both their thumbs with both hands holding the phone. The one handed typing like you're describing is an unusual minority.
Everyone is different. Long live choice.
And now Apple, please bring us a bigger screen MBA without thinking you therefore need to bump up the base specs. There is no reason not to have:
MBA 12, 14, 16, and 18", with all spec variations
MBP 12, 14, 16, and 18", with all spec variations
Sure, some won't sell in high numbers, but as long as they're making a profit, all is good.
I'll be straight to the store to pick up an 18" MBA with base processor/graphics specs and 16GB/1TB options.
