Thanks for this detailed info. (I type at similar speeds as you.) So when you use the butterfly keyboard at a cafe for example, is your initial feeling a bit of frustration (ah this again), since you did use the expression "forced to use it"...
I don't really have much of a preference TBH. That slightly less action actually translates into a bit less work... my touch lightens and my fingers move less. I don't think I could live with the 1st gen used on the original 12" Macbooks though.
