My laptop is a decade old. It's a bit slow and overdue for a replacement, but still works fine. I spent a lot of it (it was a top end gaming laptop at the time) so I decided I was going to run it into the ground before getting a new one. That said, I'm hoping I'll have the chance to get a new one sometime next year. I'm still going to keep this one, it's turned out to be a sturdy bit of kit, and while Windows is getting a bit slow on it, I'm sure Linux would run great and I could find some use for it.
My brother is borrowing my 2009 desktop with an i7 980X in it, after I finally built a new desktop after a decade or so, and he's getting some use out of it for gaming and such. It's had some upgrades over the years, so it's not "all original", the 980X is not what I originally put in it (that would've been way too expensive), I originally got an i7 920, but the 980X is still a nearly 13 year old chip and is still pulling its weight surprisingly well after all this time. With the GTX 970 that's in it, it runs games decently, but I feel that isn't even fully taking advantage of the aging CPU, it could do way more with a 980.
A decade is a long time, though. Most things aren't even designed to last 10 years. Batteries will die long before then and good luck finding a replacement battery after so long.
My washing machine is currently pushing 15 years and my dishwasher is about a decade old. That might not be the kind of tech you were thinking of, but unlike most kinds of tech, they're not designed to be replaced every few years, so they tend to last. Can't say the same for smartphones, laptops, or computers in general. Smartphones and laptops are fragile or cheaply made, and even if you manage not to break it the battery is going to die. Computers typically get so obsolete that you won't want to use them past a decade or even close to that.
Apart from those things though... Just about everything in my apartment that I actually use is 5 years old or less. My smartphone is about 5 years old, as is my dryer (cause I didn't have a dryer before then), my TV is only 2-3 years old. My various computer accessories (keyboard and mouse are modern, I have an older MX518 but don't use it anymore, I have an older monitor but also don't use that anymore as my TV is now my main monitor, my printer is probably 4-5 years old as the old one was just too unreliable) also tend to be relatively recent. I have a lot of furniture that's 15 years old, but most furniture doesn't really wear out and generally doesn't become obsolete, so that's no surprise really.
I still kept all my older tech though. I have all my retro consoles, just don't have the space to keep them hooked up. I have a couple positively ancient flight sticks, one of them being a Logitech Wingman something or other, it's old enough to have a gameport plug natively but new enough that it came with a gameport to USB adapter. It's at least 20 years old. No idea if drivers for it still exist. But I don't really have a use for a lot of the old tech I kept around, just didn't seem right to get rid of them when they're in good condition (plus I am lazy)
