The only thing in Win11 user experience wise that absolutely drives me up a wall is the new right click menu forcing me to hold shift to get the usable menu instead of the "Win 11 is smart and this new menu UI is easier to use" menu.
Other than that, it feels like win 10 (and 7 for the most part) for anything else that matters (for a normal user).
All of that being said, yes, the experience of a naive consumer buying a windows laptop is awful, but not due to the OS itself, rather the amount of bloated useless shit vendors ship with the installed OS.
As the page notes though, the real problem for kids is the devices are of course locked down:
> Important: If you use your Chromebook at work or school, you might not be able to use Linux. For more information, contact your administrator.
> (in the traditional sense, not the modern security/jailbreaking sense)
As far as I can tell, the two senses have pretty much always existed side by side. Nothing traditional vs modern about it.
