The last iPhone I bought (and am currently using) is the iPhone 15 Pro. I reluctantly upgraded to it from the iPhone 12 mini and Google Pixel 8 that I was bopping around between. The iPhone 16 updates seemed so minor, and this new round of iPhone 17 updates are equally lame. Up until yesterday I was getting ready to go in on the Google Pixel 10 Pro Fold, but then I started to reminisce about my iPhone mini, and am now also considering either purchasing an iPhone 13 mini or switching back to my Google Pixel 8. I really miss having great one-handed usability, but all of these companies have lost their way on that.
FWIW, the Google Pixel 8 is on my short list because I use, and really like, all of the Google apps (which, largely, run just fine on my iPhone, but Google offers a slightly better integrated experience with their Pixel phones). I also really like the round watch display that Google's Wear OS offers, as I consider a watch to be equal parts functionality and fashion. My Apple Watch Ultra (1st gen) is an impressive piece of tech, but the squarish display and locked-down & limited watch face offerings limit its appeal on the "fashion" end of the spectrum.
For larger-screen on-the-go needs, I'm anticipating purchasing a new iPad Pro 11 (I'll likely wait for the latest model to get announced) with Magic Keyboard. I'd then give my iPad Pro 13 w/Magic Keyboard to my wife. I tried dabbling with the latest-gen iPad mini, but I need a full-size (or, at least, nearly full-size) keyboard and decent trackpad, and all of the 3rd party options I might use with the iPad mini pale in comparison to the Magic Keyboard experience, and you don't really save any travel bulk once you start adding a protective screen cover, keyboard, & trackpad to the iPad mini as compared to the iPad Pro 11 w/Magic Keyboard.
And for still-larger (and more powerful) needs, I've got my recently-purchased MacBook Pro 14.
But back to the phones...It sucks that I need to compromise and go with older-gen technology in order to get an optimal one-handed UX and a minimally-sized (pocket-friendly) phone. A Pixel 10 Pro mini or an iPhone 17 Pro mini (and new round-faced Apple Watch) would be my ideal options, but neither exist.
