> A throwback to the 90s to early 2000s would be fine. That's when they got it right give or take a few things such as multiple workspaces.
Back in the 90s ubiquitous networking wasn't a thing yet at the consumer level. Getting network transparency in Windows still seems to be like pulling teeth.
A few other random things that I can see no justification for:
* Very limited keyboard input choices, compared to Linux and Mac. It seems that you are limited to the basic 100 or so keyboard symbols, and from there it is Alt + numeric keypad all the way. If you need proper typography without using your word processor as a crutch, that is kind of important.
* Weird limitations in file naming and case conventions (from memory, no colons, no case sensitivity, no question marks, …)
* Weird file locking limitations built right into the OS?
* Lack of multiple workspaces.
* Single clipboard with no history.
* Lack of basic tools, such as a working text editor, SSH client (and SFTP?)
* Lack of proper synchronisation between phone and desktop (clipboard sharing, making and taking calls from the desktop.
* The strange patching system that prevents people from shutting down or logging into their laptops. Or forces them to reboot.
