> Want to easily share files between your PC and iPhone?

Just plug it in: https://support.apple.com/en-us/HT201301

You define "easy" as using a USB cable, but most people would think that cloud storage is easier. You can do that too:

Those solutions don't expose the phone as a storage drive like Android phones can, though.

> Connect via USB to a PC as a mass storage device

... if you want a mass storage device... buy a mass storage device?

Personally I'm happier with the cloud though. I want all my files in the cloud anyway as an offsite backup, and the internet is generally fast enough that I can access the remote copy whenever I need it.

> Be switched on immediately when plugged in, after the battery runs out

My battery never runs out though.

But seriously iPhone CPUs are pretty power hungry with 3.46Ghz with six cores and aside from just booting up there's also some pretty high decryption going on to decrypt and verify the operating system hasn't been tampered with. I'm pretty sure a USB cable can't provide enough watts.

> Want to use a keyboard/mouse/monitor to control your phone instead of your thumbs

USB and Bluetooth keyboards totally work with iPhones, and iPads. I use a mouse and keyboard all day long every day with my iPad (I'm happy with my thumbs for my phone, but I could use the keyboard for that too).

And you can absolutely connect it to an external screen too, with HDMI or over a network connection.

> if you want a mass storage device... buy a mass storage device?

Eh, I bought a 128GB device that is practically always with me which already has a lot of my important files on it (my phone). It can be pretty handy to just be able to plug in as a mass storage device, but tbh these days I mostly just use things like OneDrive or Google Drive for keeping files accessible on the go. But when I'm wanting to shuffle a big file around between machines that aren't networked, its a handy thing. That, and being able to poke around the actual filesystem on a full-sized computer is handy.

> I'm pretty sure a USB cable can't provide enough watts.

I've got a 65W USB cable in my backpack, it came with my laptop to charge. Its not even the most powerful USB cable I've used, my friend's thunderbolt eGPU dock can do like 100W or so. I can't imagine my phone could pull 65W for more than a few seconds without literally melting.

This limitation of the Files app glaringly omitted in this workflow still gets my goat https://apple.stackexchange.com/questions/444977/how-can-i-g...

You're saying "can't" like your points are technical limitations instead of product choices.

For what it's worth, my brand new washing machine still can't make my morning coffee, either.
