I'm still undecided. I'm pretty tied to the Apple ecosystem at this point, for better or worse, so jumping back to Linux is a tough sell right now. I already have a touchbar MBP, so for me it'd be solely about the extra RAM (which I really need) and speed bump (which is nice, but of lesser concern). I haven't had the keyboard issues yet, but have some concerns.
I probably will end up getting one but not immediately--that said, it's highly likely I'll get a dedicated Linux laptop as well and start looking into tool replacement and integration options in case it ends up going that direction.
