2019, with the LTS version of Kubuntu (18.04 at that time). Moved when Windows 7 EOL was announced.
The hardware I specifically had trouble with was a Brother MFC-9320CW, a Kingston MobileLite SD card reader and a TP-Link TL-WN722N WiFi dongle. All ostensibly supported, all janky to the point where I just gave up and installed Windows 10.
I also had some Intel Atom Laptop with Arch and i3wm. I didn't mind that so much since I only ever used it for a few specific functions and none of them were critical for my usual workflows. It also flew with i3. I do remember both the WiFi and CPU power management semi-regularly fucking up though.
You can be as smug as you want with your "2003" comments, but the reality is that it's simply not fit for purpose as a general purpose consumer OS.
