The last reliable laptops I had were IBM T40 (my first one) and IBM/Lenovo W500. I ran a bootstrapped software company and they didn't fail me. After that I briefly had a Samsung ultrabook (that was semi-reliable) and then a Dell XPS 13 that one day had a screen crack when I opened it. Then I switched to MacBooks when M1 came out: first keys got stuck in my M1, then the screen bezel spontaneously cracked on an M2 just when the warranty ended and I was in Europe. Apparently now Apple laptops are luxury items, you have to wipe the keyboard from dust before closing the lid.
I do not care about cost, I just need something that won't suddenly break when I am abroad and need to do something important. I miss those American IBM ThinkPads.
