I totally changed my KDE themes to be XP-esque, sound themes and all, just to have the good parts I missed, but keep a usable OS haha.
M$ has done and continues to do a lot of terribad things, but XP wasn't one of them. Computers felt fun back then.
....Minus all the security issues. That's gotten better with time...
Edit: Oh yeah there's a subreddit of people modernizing XP and making new drivers for it and stuff LOL
