Modern hardware feels more disposable despite costing more

One thing that feels strange about modern tech is how expensive devices have become while somehow feeling less permanent.
Phones cost more. Laptops cost more. Smart home devices cost more.
Yet a lot of them don't feel like products you're expected to keep for a decade.
Batteries wear out. Software support ends. Parts become difficult to find. Repairs can be expensive enough that replacing the device starts to make more sense.
What's interesting is that some older electronics felt built with the expectation that they'd be around for years.
Meanwhile many modern devices seem designed around upgrade cycles, even though improvements between generations are getting smaller.
I'm not saying hardware quality is worse.
In many ways it's better than ever.
But there's a difference between a product being well made and a product feeling built to last.
Sometimes it feels like we're paying premium prices for devices that companies expect us to replace sooner than we'd like.
Do modern gadgets feel more disposable to you than older ones, or is that just nostalgia talking?
