But in general, I don't type on the Macbook when I travel. I usually have an ergo set up with a portable keyboard and touch pad and laptop stand.

I find it odd that you say it's fine if you're "forced to" use it, like your standard for a laptop keyboard isn't one that you should be able to use regularly (and you mention bringing your own). was wondering why you have this attitude...
I type just as fast on the butterfly mechanism as any other, a consistent 90wpm with no mistakes and scattershot up to about 130 wpm during programming. I've been at this speed for about 2 decades now, going all the way back to using a vintage model M keyboard, an AEII keyboard, etc.
I sometimes go back and forth between my newer MBPs and a 2014 I still have. It takes about an hour of adjustment to get my speed up when switching.
