I mean this is what https://reddit.com/r/ergomobilecomputers is for . Try searching there for ‘sonshi’ setups so you can just put a small ergo keyboard on top of your MacBook.

one example is the corne: https://Reddit.com/r/ErgoMobileComputers/comments/u3xcfb/ergomechkeyonlaptop_corne_foldout_travel_case/

Interesting to hear the pop socket helped with the phone! Been meaning to just wean my phone use but may consider that.

Thanks for sharing and nice to hear the argument that " a split keyboard is absolutely 100% mandatory"

Yeah, part of the reason I’m asking is because I was originally set on a rather subtle design (split monoblock with a bit of angle, not much space in-between). I had some slight pain on occasion but largely viewed many users on here doing more ‘preventative’ setups.

The recent pain has been making me ask myself again whether to do that approach or go for a more complicated sparatable split design. I’ve used fully split setups before but they weren’t travel-friendly.
