Both Apple and Google are resisting that future. Samsung seems to the only one embracing it.

Android has Desktop Mode now - https://www.androidauthority.com/android-q-desktop-mode-demo...

Just to be clear, that is 5 years old.

Just realized that Pixel 8 does have display out. So Google is now embracing the future.

Microsoft has been showing that kind of integration in videos about the future of work for at least a decade: https://youtu.be/SO49Q-HcuKE?si=iCYcBh-a9RmODiVf

I mean you're not far off, I have clients who are pretty much all in MS surface + peripherals as their primary workstation for their employees. Similar thing with some clients and chromebooks/google workspace, not quite phones, but the idea of a portable device docked into a station is pretty much the norm. I've seen huge portions of different businesses barely rely on computers to be much more than a vessel for a different flavor of enterprise related apps

dock to what, and why? and why a mouse? the thing already has a touchscreen. If you want to type faster you can buy Bluetooth keyboards and stands for your devices today, including some Bluetooth keyboards that have a little slot in them to hold your phone or tablet.

If you have enough money to have the space for a desk with a keyboard, monitor, and screen, the cost of a dedicated computer to plug into it isn't going to be an obstacle. I think this is the reason we haven't seen docking take off.

We're really close to that already. (I haven't seen a desktop computer under a desk in years -- basically every modern office, is a bunch of perhreprials on a dock, tied to one single USB-C/Thunderbolt cable, that gets plugged into a laptop.

If iPhones / iPads ever get macOS or equivilent, I'm pretty sure people would switch. It's mostly an Apple-enforced rule preventing it, not necessarily any actual software or hardware.
