The ergo community loves their 40% keyboards. The reasoning is that your fingers can not reach large number of keys anyways without moving the whole hand, and by eliminating the hand/wrist movement you can be more ergonomic even if it leads to more keypresses.

Same thinking can be applied to speed too, hand repositioning and finger-stretching are not fast things to do, so concentrating functionality near home positions allows you to do the keypresses very fast which trades off the number of keypresses.

This all said, I personally haven't used such keyboards, this is more of second hand impressions

I thought the ergo community loved their split, ortho, big ass keyboards? I just bought an used Kinesis (the simple one though), love to see if it improves my wrist pain.

I see lot of love for Corne (and similar) keyboards, and 3.6k GH stars attest to that: https://github.com/foostan/crkbd

What are you basing this on? Every serious ergo keyboard I've seen is a split keyboard.

I'm just grouping in general 34-48ish key keyboards into "40%" category regardless if they are split or not or something in between. So popular designs such as Corne falls in there.
