If there was a possible strategy for Microsoft to get into the mobile game, this would have been it.
Their first pass failed to really optimize for mobile at all, so you had mobile devices with clunky interfaces.
Then when they finally saw that a more targeted UI for mobile was needed, they went the other way, screwing up desktop by trying to make it look like their vision of a mobile OS, all while having the phones still unable to use monitors so there wasn't really any 'synergy' between the platforms despite throwing the desktop experience under the bus.
Now I've seen samsung and motorola phones drive desktops, but good luck which ones actually support displayport alt-mode on the usb-c.... However not *too* much of a loss because they both have just utterly shitty window managers with no options to swap it out for anything vaguely more capable despite a plethora of options in the space.
I think Android has at least got *some* of the message with respect to applications, carrying over from the ChromeOS support for linux applications, however it was sad that even as a pure linux person who uses desktop linux without a hint of Windows, I actually thought using Linux under ChromeOS was even worse than WSL.
Now if by some miracle, I can have an Android phone with displayport that will let me run Plasma desktop in a normal way, they can take my money so fast. Of course, realistically speaking, they'll have like 3 or 4 people excited for that and wonder why they wasted money pandering to us..
