Micron-optimized keyboard sounds like horrible reliability. Speck of dust and laptop is ruined (Surface laptops can not be repaired in non-destructive way).

I had 4x Natural 4000 keyboards, they had constant problems due to bad design. Space bar got stuck. Keyboard wiring was prone to corrosion and shortcuts, keys would randomly stop working. Had to disassemble keyboard, wash inside with mild acid and leave it to dry.

At end I did this repair once a month and had multiple keyboards on rotation. I put up with that, there was no alternative at that time.
