It looks like the one feature I was more eagerly awaiting is there: It can drive a display through the USB-C cable ( https://www.apple.com/iphone-15-pro , scroll down to "Gigablast your gigabits" and then click on "Explore Connectivity". Looking forward (assuming it will work like the iPad Pro) to not carrying a laptop with me when I know there is a USB-C or HDMI (with an adapter) screen available at my destination.…
I hope this is true. Even with a Keyboard and mouse and I can browse Internet with it would be great.
Mice are a lot more annoying, because they're part of the assistive devices, so you need to enable Assistive Touch, and then you either have the mouse connected or the Assistive Touch menu taking space on the display, which is probably not useful if you're abled. If Assistive Touch is disabled, the mouse "works" but you don't get a visible pointer which is completely stupid.
Possibly connecting to an external display won't have that issue, or iOS 17 will make the experience a bit better for non-assistive mousing.
