Not at all impressive, but to maximize interactions on a newborn thread:

It's probably my PS3, which I would have gotten Christmas 2008 (or maybe it was 2009?). I recently started sailining the seas, and the most convenient way to watch those videos is to burn them to a disk, and so the PS3 is really just a glorified DVD player (can't even be bothered to use it's blue ray functionality)

My paternal grandmother's KitchenAid model K mixer she bought just after my grandfather returned from WW2. She gave it to my mother in the late 70's because she wanted a new one and the damn thing showed no signs of dying. My mother gave it to my wife about 15 years ago for the same reason.

We've bought some new accessories but that fucking zombie mixer will outlast the roaches.

I have a General Post Office model 711 telephone. I installed a microcontroller into it and it's now the keypad for my home alarm system. It's also hooked into Home Assistant so I could have it for other things if I wanted.

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 late version (early 90s) Quad 34 preamp.

It's a brilliant and somewhat unique design. The eq is part 8 pole tilt filter and part lift/step filter with adjustable turnover. This enables you to position the audio in a very precise and uncoloured way, much like changing your seating position in an auditorium. If you like bass you don't sit at the front!

It has a true mono selector, high and low frequency filters for radio and vinyl subsonics respectively, a modular phono stage for MM or MC turntable cartridge type, and the volume gain stage is accurate between channels to around a tenth of a dB, which is about ten times better than is generally accepted as adequate.

It's power is so efficient that it never gets even warm and it's audio design has a quality that is similar to the way valve equipment sounds.

It's a very special part of my system which drives my active speakers. They are pro audio which have a very accurate response compared to consumer speakers. The Quad gives them something special to reproduce which, with a lot of CD sources imparts a bit of character that's musical and very pleasant.

If it ever needs servicing, I can take it to the Quad service centre where it was made in Huntingdon near Cambridge, a couple of hours drive away.

I'm very proud of my Quad 34, I wanted one for many years and was fortunate to be able to find a good one I could afford at the time. I expect it will outlive me, along with my speakers and a few other bits and bobs I've collected over the years. It's the oldest bit of technology I have that I use regularly. I have a film camera that may be older but I don't use film any more and I thought the Quad would be more interesting.

Thanks for asking and I hope you find this worthy. I'm happy to answer any questions about all this if anyone feels compelled.

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.

I still listen to my music using a 160 GB iPod Classic. Apple struck gold with that clickwheel. Carrying around a dedicated device for music just for that elegant one-thumb control I don't even have to look at to use is still totally worth it to me.

An Acetronic MPU1000 games console, from the 1970s - 76 or 78 I think. Still worked last time I powered it up, I also got some extra games cheap off eBay a while back, interesting playing something other than the three or four games I remember from childhood.
