As someone also trying to get out of (or at least less dependent on) the Apple ecosystem, the laptop market sucks! Everyone but Apple is making the same garbage-tier, shoddy, plastic laptops with bottom of the barrel components that I'm sure are engineered to just barely work enough to avoid immediate product returns.
I'm starting to accept that if I want a development workstation class machine, I need to build a tower from components.
When I walk into those kind of shops I press a few keys of every laptop and check which keyboard flex. Usually the cheap laptops flex and the expensive ones don't. By cheap I mean 300 or 400 Euro and by expensive I mean 800 or 1000 Euro or more. Some laptops that flex are made of metal, some that do not flex are made of plastic. My HP ZBook 15 from 2014 is rock solid and does not flex even if it's mostly plastic. There is a catch: the keyboard is built with a sheet of metal on the bottom, so it's very rigid. The laptop itself has a frame of metal and a shell of plastic. It's definitely not light, one of those laptops in the 3 kg category (6 lbs?) and definitely not cheap. It's also built for total repairability: it opens with no screws and I can replace everything even the CPU and the GPU l. I replaced the HDD and the DVD with 2 SSDs, maxed out the RAM to 32 GB and replaced the keyboard many times, when keys eventually wear and start to fail. I'd buy it again, with modern components (NVME bus, DDR5 RAM) and without the number pad so I can center the space bar and the touchpad.
Magnesium and plastic burn better.
Also aluminum is quite good at heat transfer.
Wait....
I've been considering Framework or System 76 when my Macbook Pro finally dies.
But that means spending ~$1600-2000 (though, about how much my MBP cost).
It seems to take some good research or a clutch recommendation to spend less than that while getting what I want. And I don't understand how 1080p is still such a common resolution.
When you walk into a Best Buy, the small majority of non-Apple laptops seem to be made of metal, even the $300 Chromebooks. They look and feel more premium, but probably aren't.
The sad thing is that plastic should be the best material to make laptops from. It's lighter, and it gives when dropped. Think about the cases everybody puts on their phones. They're not made of solid metal, for good reason.
The old Thinkpads had it right, they used a magnesium frame surrounded by high quality plastic.
My MacBook Pro is well made, but it's also a pound heavier than it needs to be.
