Most Linux distributions already run on MOST laptop platforms, incl the Apple Macbook. Unless you have a very specific application that runs on Windows/MacOS or you have some employment requirement, EVERYBODY would benefit from running a Linux distribution. Very usable even on old hardware.

You can even get Linux Distros that have the look and feel of MacOS. Never been a fan so they don't interest me but it can be done. They all have OpenSource versions of LibreOffice that are either installed by default or as an option. They run Firefox or Chromium browsers (OpenSource Chrome), and Google Chrome is an option if you can't live without it.

absolutely,

I think, in my quick post i was perhaps a little vague,

The idea would be to do something active, like right now, not in 25 years, around the 'compositor', maybe take a hard look at Vulkan.

This would allow people to use a stable baseline & up to date hardware platform (the example of the mac-book pro type hrdwr)

with a FULLY functional protocol, so that we could use ANY Linux,
not just being bottle necked into Ubuntu that they have been teaching all the new guys on over the last few years ..

1. base line hardware,
2. fully functional rendering/compositor etc
(on par if not better than dx12)

This should give people the 'no OS lock in' ability to run (fully functional) software same as windows, across any Linux.

I am not talking about a quick hack.
Its been a pipe dream for Linux heads for years,

This concept (not new) would unchain not only apple tree, but also windows domination and limitation of choice.
