> no monitor during the XP era would've been a CRT one haha

Well, not really, and it depended highly on the place of work/study and country/state. For example, my University replaced the CRT ones with LCDs only in 2005-06 (they've used XP in computer rooms for quite a long time, skipping Vista and 8).

I myself used the CRT monitor with winXP until the late 2004.

some of those redditors don't know what they're saying then, huh? thats such a good point - couldn't I run XP on a CRT monitor today if i wanted to

Nothing stopping you from using one with totally modern systems as well, except for the ever increasing prices, I guess. Anyway, yeah, same as some of the others already mentioned, but I don't think I actually owned any sort of standalone display—be it a monitor or television—that wasn't CRT until ~2009 or so?

I used my mom's iMac G3 (CRT) probably until 2004 or so, because I distinctly remember getting stuck on Tutorial Island on RuneScape as a kid, since you had to Right-click -> "Prospect Rock", and at the time, I had no idea how to actually do it with Apple's single-button mice lmao.

Aside from the couple of laptops that came later, I don't think I had moved on [for the worse] until a bit after I put together my first DIY computer (Phenom II 920, etc); I still had a CRT TV in my room long enough to have been using it when Halo Reach came out.
