If we're including family consoles, I'm gonna say the family wii my family got in the late 2000s. I was actually pretty pissed when we couldn't find it when it was in temporary storage because there is one mii that I would have been absolutely furious with myself if I couldn't remake it on my switch. Luckily we did find it and I've managed to recreate all the miis we had on there onto my switch, especially the one mii my grandma made.

Not tech exactly, but does a 22yr old Vicks inhaler count? It's somehow stuck around through every move, and I can still use it when I have a stuffy nose. It's kinda nuts...

My gas stove with an electric oven. It works, but barely.

I have an old CD Walkman that still works just fine. Although looking at the logo alone, it's most likely made after the year 2000, so it's not that old.

Mine’s the 390t with 256mb of storage. So it’s one of the ones that’s triangle in shape with a real smal lcd screen and takes a single AA battery. Suuuuper simple to just plug in with mini USB and drag and drop mp3s over.

A Galaxy S5690 Xcover phone from 2011 as reserve phone, software modded to be nice and fast. Not ancient, but as a reminder of what you could do with 200MB RAM (300MB is reserved for system) and 150MB internal storage. Btw, standby time is measured in semesters.

My dad is farmer, he has a water pump from 1971 still in use.

Probably my Canon 5D Mark II DSLR that I bought at launch (2008). Still works fine hundred of thousands of clicks later, multiple trips across the world, etc etc. It even still holds a candle to my current camera on the photo side of things (video specs definitely dated now though).

GameBoy Color with a single game: Pokémon Red.

Next time I was able go to the shop they had upgraded to GameBoy Advance and no GB/GBC games were to be never found again. It was the best/worst thing I ever got. :'(

I have a spring/crank music box stuffed animal from when I was born (several decades) that still sounds perfect.
