Last night I was reading about others' problems with this keyboard. Some people mentioned that the Canned Air (TM) and slamming keys were enough to "fix" it. So I applied quite some TLC to the space bar.
After it registered twice four times today again... I found a skin for Windows that makes it look almost like macOS. Grinding my teeth, I will buy a Windows license for Scrivener or install macOS in VirtualBox (Scrivener isn't exactly CPU-intensive). Adobe CC isn't platform-specific. As for touch bar, I've been laughed at in another thread for saying this, but I will miss it – I configured it with BTT exactly how I wanted it.
Yes, Win 10 October update killed a lot of computers including *deleting their Documents folders*. Yes, I think File Explorer looks gross. No, I can't afford to own a laptop that might require repair at any random moment because keyboard will stop working.
I wrote to Apple Executive Relations again, but truth is, there's very little they can do for me bar perhaps giving me a free Macbook Air. Right now Apple no longer produces any portable computer that I would trust when it comes to typing a lot, and I am not spending 1000 euros on 2017 Air when for 2000 I can have a Yoga C930 convertible with 4k screen, i7 CPU, 16 GB RAM, upgradeable 1 TB SSD, 2x Thunderbolt 3 to use all the USB-C I bought for the Macbook Pro (har har). I know I will spend a lot of time fighting Windows, probably discover that I missed 10 macOS apps that are totally necessary for my productivity, etc. But I won't constantly worry that I'll be on a deadline and right that moment "E" will stop registering altogether.
On the plus side, I won't spend much time on Macforums, and that will definitely increase my productivity, perhaps saving me almost enough time to fight Windows' bugs!
