> iPad Pros also use USB C, so they already have the requite support on the portable electronics side.
It's always been there, lightning is just a connector, the physical protocol is USB.
> Personally, I think apple has wanted to switch to USB-C for a while on iPhone.
Yes, but also after the DC -> Lightning transition they kinda promised there would be no new transition for a while, which was pretty safe at the time, but USB-C landed a few years later.
I actually expected the iPhone 14 to switch, as 2022 is the 10 years anniversary of Lightning, and about how long the Dock Connector lasted (although technically it survived until this year and the discontinuation of the iPod Touch).
