It's repairable, upgradable (MB swap for processors (3 generations of Intel and one AMD so far), ram and storage are socketed), linux support is fairly good with most things just working (running NixOS personally on my 12th Gen Intel 13").
Performance is average (but the i5 I got was a improvement over my 2012 Retina MB Pro) and battery life is average to poor (but I am plugged in most of the time), size and weight are okay (for me!).
So I'm moving on...
My advice, just get a Mac, I pulled the trigger on an M2 Air this week. Macs are very popular with devs and will be capable for many years.
A year and a bit on mine. Cable is still fine but like I said though it's plugged in all the time and don't really travel with it. I generally leave the cam and mic switch off so no experience there either. Performance was a step up for me and in a year or two I'll get what ever is current for AMD so it'll be another bump.
A Mac would have been at least an extra $1000 (CAD) and isn't upgradable so I need to pay the Apply premium on RAM and storage up front to future proof.
Like you, I have it plugged in all the time, rarely travel with it. The cable frayed at the right angle.
