I still have a monitor on my main setup that uses DVI because I'm too cheap to upgrade.

I occasionally harness fire. Does that count?

I own a balance scale, I was getting sick of dying batteries in modern ones

I listen to radio

I still use clippers bought in 2015

I got a rock I use for smashin sometimes.

I love an automatic mechanical watch. Still use CDs. At work I occasionally need to use 3.5" floppy disks. Still read paper books.

Lenovo Thinkpad X200t by your intended meaning. I don't know if my Meade ETX-60 is older... might be... I haven't checked date codes or anything, but I have several microprocessors and discrete logic chips for breadboarding. Probably, the oldest is a tossup between Z80, 6502, 8088, 6800, 68k, or some CD4000 series logic. Maybe a few of my 74xx chips are older. I have a little bench power supply that was made in the 50's somewhere in my closet. I have a Wander bike my family put in storage that is from the 40's or early 50's.

Newspapers, online news is an echo chamber of personalized content

My clock radio alarm is from the late 80's, I guess. It was my Dad's before and it still works fine.

Do you mean oldest as in invented the longest time ago or oldest as in that specific technological artefact that i use is the oldest one i have?
For the first one i guess cooking?
For the second one its definitely my microwave oven, made in 1991.

Headphone jacks and BNC connectors for computing. For hammering things, a rock sometimes.

There's a few appliances that we refuse to let go. If it ain't broke, don't fix it. My wife loves our early 1970's General Electric range. It's got push button controls that are built into the range hood. That was actually a brilliant idea since it keeps the controls from getting all greasy and my little kids can't reach them.

Our old vacuum, a 1953 Kirby (which I've had for 25 years) has been semi-retired. Our house has a 1970's Kenmore central vac. Just put a new motor in it last year so it should be good to go for a while, hopefully.
