My need for this new iPhone is driven by my declining vision. Twenty years ago, I had no problem with my first iPhone. Five years ago, I started to get acquainted with some of the visual accommodation measures in iOS. I do still use my (physically larger than I would like) iPhone 16 Pro Max, which I bought for the biggest screen. I'd love to do my stuff on my laptop or desktop, but smartphones are de facto The Computer these days. So I'll probably buy an iPhone Duo after I sell a kidney for financing. All that said, today's Apple presentation left me gobsmacked at the technology they've developed. I was born before civilian jet transports were in service, with all that implies for a long personal view of tech dev. The tech feels to me like a cut&paste from 2076.
And why should we all have to buy big ass phones because your vision is declining? Nobody argued big phones shouldn't exist, it's just small phones currently don't.
