I want something like this. But realistically I’ve had Samsung Dex for years and never use it. I liked the idea of Continuum. Leave my phone in a dock and magically it shows on the monitor and I use my mouse and keyboard. Again, no real life use case.
Dex,Chrome OS, whatever distro pinephone and librem use, they all feel like I’d be having a lesser experience than using my iPhone or iPad. I don’t see this changing until Apple or Google decides to make the phones capable of handling apps in a desktop-like experience and environment.
iPadOS 26 is very close to that vision. I can’t run that on my phone, but it is almost that perfect portable ubiquitous computer!
