My grandma (about 80 yo) has been getting more and more annoyed with windows 11 and all its bullshit. Pretty much everything she does requires either a web browser, a file manager, a word processor, a spreadsheet editor, or a combination of the four. Within the span of an hour & a half, I got her windows 11 install replaced with an install of Fedora KDE, and got all of her files/programs/etc. transferred over; everything was basically 1:1 with the exception of swapping Word/Excel for LibreOffice (which she said looked very familiar and wouldn't take long to get used to). She's already commented on how the system feels more usable and "less annoying" than modern windows. She was getting really fed up by the constant pestering to enable OneDrive, Copilot, updates taking 20+ minutes, etc., and her aging laptop starting to slow down; it feels like a whole new system now, and she's noticing it.
Of course time will tell how things go over time, but I can't thank the developer community enough for making this possible in the first place.
