I’d be interested to see a breakdown of reasons the keyboards failed for each model year.

And what percentage of the pre butterfly design were because of sand/dust etc. then contrast that to the butterfly design percentage. They could have merely improved reliability in another way(s) with the butterfly design.

That would certainly be interesting -- from your other comments comments in this discussion it seemed like you already knew the answer! Guess I assumed too much.
