You can upgrade SSD on most laptops other that Mac.

My Dell XPS13 came with a 1TB SSD, which recently was replaced with a 4TB one...

Never seen a device with soldered storage that is a laptop and isn't an Apple.

And the reason why RAM is soldered is because they need the signal integrity to run "high performance" graphics on it, it's not (just) because the manufacturer hates you. This is why FW desktop has soldered memory too.

LPCAMM is coming, which is an interface with better signal integrity than SODIMM or whatever they're called, I hope it will bring RAM upgradeability back to office machines. I really only need to render videos and a slightly animated WM on my laptop so I don't care for HIGH PERFORMANCE AI IGPU when I have a desktop at home.

eh, while not fitting ragebait, plenty of Lenovos, Dells, and HPs have upgradable hard drives and not few have upgradable RAM and WiFi modules too. I'm writing this on a 2019 Lenovo P2 that I upgraded both the RAM and nvme on it.
