Phones are also becoming more unserviceable because of the requirements for waterproof cases. Repair shops lack the ability to restore watertight seals.
If you want a watertight phone, that does come with the territory, that's for sure.
But heaven knows that there are plenty of other options available.
I had the fun (and, yes, it was my choice and, yes, it was done for my education/amusement) of replacing the keyboard only on a top unit on one of my laptops that was originally affixed by plastic melt rivets. I'll take ever-so-slightly thicker, thanks.
But it really hit me when I was dealing with my partner's ancient, consumer grade Toshiba Satellite c55 series just how much lighter, thinner, and (often, but not always) cheaply-made new laptops, including my own, have become. That thing had been through hell and survived it with aplomb. It's certainly not difficult to carry, but when you pick it up and then pick up any machine produced in at least the last 5 or 6 years, it felt like a tank. It also had the service bay doors that I do so miss.
I'm not under any illusion that much of what I'd like to see come back will ever come back, and even if a small part of it were to do so it will likely be the direct result of "right to repair" laws, much like USB-C universality which was on its way is being majorly pushed by legal developments in the EU. I've never believed that "the invisible hand of the marketplace" alone gives the best results.
'Well-regulated free markets' is not an oxymoron, but a necessity for good economic outcomes.
