Latest update about my fourth MBP18 is that I can't make up my mind about it.
A few days space bar started acting up. Unshaky caught 30 repetitions within six hours or so. Then E key registered twice a few times and I was like, well, X1 Carbon Hackintosh is my future, I guess...
...but then the keyboard stopped doing whatever it was that it was doing. Unshaky is still on, yesterday within eight hours of typing it caught two double-presses which actually COULD have been my fault, one typo per four hours doesn't sound like the keyboard is broken. I've still got 10 days or so to decide. But right now I am thinking I'll keep this MBP, and when in the very unlikely case the keyboard breaks again I will send it to repair, get an Air, and return it before the 30 days pass.
Truth be told, though, if I didn't use macOS only apps, or simply Mac apps I paid for already I would now be brainwashing myself into loving Windows. And it might still happen, because a similarly specced Windows laptop would cost me €1000 less, and that is a LOT of money to spend on Win software 😛
I would love it if Apple could somehow be forced to reveal how much money they lost on keyboard replacements so far since it's impossible to estimate how many sales they lost. Lenovo and Dell must be sending Ive flowers (very thin and white only) on weekly basis though.
