In 2023 it's really easy now. Honestly the install process like 9 years ago was easier than windows because you got a proper Gui.

90% of shit runs in a browser now. Browsers have been fine on Linux since forever. I still game and video edit with a professional editor no problem. Just give it a whirl on a spare disk or something, I promise it will likely be painless :).

Not much to "learn" unless you have quirky hardware that doesn't have proper drivers but most everything works out of the box these days.
