I have some 30 year old tech stuff lying around, like one of those MS forcefeedback joysticks, but never use it anymore, the same for the collection of old smartphones. My smartphone/tablet is 6 years old, so are two of my mini PCs. But some other devices are significantly newer than that. Some of my 3D printers might be a bit older, maybe a decade. One of my Eizo monitors is 11 years old... I might reuse my 11 year old workstation for the occasional task.
The issue with most of the old tech stuff is, it just isn't that good anymore, it draws a lot more power, bulkier and heavier. Imho no one is rocking a CRT TV anymore, unless you're a hardcore retro gamer. The same goes for old consoles. We started on an old Atari 2600 in the early 80s, which was really cool at the time, the same goes for the C64 and the Amiga 500 we got, and as a child I went on vacation with our GameGear... I still feel nostalgia for those things. And no matter how cool a GameGear looked, I'll live vicariously through the YouTubers that share their hardcore retro gaming experiences. For the retro stuff, I emulate, I have a Retroflag GPi Case (one that looks like a gameboy), it has a RaspberryPi Zero 2W in it and is more powerful then any of the old consoles. For that GameGear 'experience' I have a Steam Deck and can play old retro stuff on there or modern titles like Diablo 4 or Path of Exile 2... Looking at how big and how much power my 11 year old workstation draws, then looking at my modern Mac Mini M4 Pro, it's day and night and see very few reasons why I should continue to (daily) use such old tech when I don't have to.
The days of having to upgrade your PC or replacing your smartphone every year or two have been behind us for a decade or two... So I personally do a lot longer with smartphones, tablets and PCs then I did 25 years ago. But there is a limit to that, and I doubt that many are rocking 30-40 year old tech as a daily driver... Heck even cars are considered old at that point!
