I've seen some recent examples of XP in the wild, they pop-up occasionally in old ATMs, bus route displays, small stores running a PoS, etc. Not a recommended configuration of course but still happens nevertheless.

For me I enjoy it as a fun/hobby OS. I can install all my favorite tools and games and boot it up whenever. It's also fun to see what modern work can still be done on old OSs. Recent versions of PuTTY work so I can in theory sit on my XP box and drive LLM agents with Winamp playing in the background, chat on MSN with Escargot, etc.
