Honestly I don't get why we are always getting this nonsense from peopl about the "Linux desktop" needing to be more like iOS & Android and clearly not getting why that will never and can never happen without it no longer being the "linux desktop".
iOS and Android appear to work well because they are "strongman" platforms. Where Apple or Google/Manufacturer/Carrier are the respective "strongmen". There just _is no_ strongman in the linux ecosystem. Who's going to be that strongman? You?
And besides, any such system would be an anathema to the freedoms & power a "linux desktop" is supposed to give you - and if you're not interested in them, you've got to ask what it is you really want. Is it that you want a linux kernel powering your (or your mother's or whatever) desktop? Is it X? Do you have a fierce desire to see gtk powering half the world's desktops? Because if you just want another Windows or Android, Windows and Android are there for you.
"Android has massively more hardware vendor support."
I don't call "I'm stuck with an old OS because my manufacturer can't be arsed to port anything current to my model" hardware support. It's dodgy crap barely working on a couple of releases. It's the dark ages of hardware support.
