Apple doesn't want to build a version of dex. I don't know why, it seems like an excellent fit, but they don't care. It probably has to do with the fact Microsoft's attempt has failed miserably.
If you care about this concept, I'd recommend considering buying a Samsung phone instead of an iPhone. Web browsing, office work, remote desktop, terminal stuff, it all Just Works hooked up to a compatible dock. The desktop feels a bit like a polished Linux environment, with deviations from Windows and macOS in the way things like the launcher works, but it also feels very finished.
The only real limit I've run into is the amount of RAM packed with these devices. The 4GiB of RAM my tablet packs clearly isn't enough to run multiple browser tabs, hires video playback and a fully featured MS Office at the same time, but I also imagine most computers would struggle with 4GiB these days. The S23 contains up to 12GiB of RAM, I imagine that'd be a breeze to work with.
I think people who care can use DeX for real office work today. I imagine the people who care are a minority, though.
No thanks! My phone has 12GB; I'm going to be using that for general computing and RDP into my Macbook when I need to.

The fact you can use the stylus that comes with the tablet on your PC through the second screen feature is kind of nice, but the wireless issues make using it kind of a bother.
It can’t?
I mean, I’ve got better desktops (all of which are actually laptops) so I rarely use the phone this way, but my phone can with just an adaptor to plug in HDMI and a keyboard & mouse, and the Apple fans are always telling me how much better iPhones are at everything…
