Ubuntu is pretty much mainstream, if a person can figure out how to use Windows or Mac then they can figure out how to use that. A lot of my family is going to have to pay someone to work on their computer no matter what OS is on it if something breaks so it doesn't really matter. I also keep backups of my important stuff on external drives and occasionally a DVD-R, any OS can be used to access that.
Once upon a time I used to "think" that debian and/or RH and/or SuSE..
and or ... fill yourself.. would be mainstream.
Then.. obviously "the desktop" metaphor brought me back to the land where GPU vendors and hardware fabs are integrated into a cash flow network where they will not allow any other mainstream to reduce the rate of cash (flow)
In other words... if they can not launch a "new GPU" a "new MOBO" every 15 days requiring a "new OS" and new license.. well they just will not allow other landlord mainstream.
Now comes de facto the mainstream where the very same model will apply
Embrace (done) - Extend (fully done) - Extinguish will soon be done ..
https://linuxiac.com/microsoft-cbl-mariner-linux-1/ Expect the MUD where Wayland compatible layer will implode XOrg
Vanishing all possible scenarios where a distro *not compatible* w/WSL
will exist ..
So why someone choose anything besides this aberration "MARINE" thing
running inside the bundled WSL thing?
Extinguish is soon on the horizon by imploding XOrg and taking over
*NIX "desktop" completely to the mains stream.
Welcome new Merdsoft Linux on all hardware already bundled by vendors.
No need to have anything else.
*NIX and XOrg are already a complete obscure MUD ..
promoted by these things not *NIX and not anything else...
just MerdSoft *NIX
PS> try to compile the latest MUD on XOrg freedesktop.. see for yourself
what they have done from the inside..
