The main question should be: are split keyboards any better than normal keyboard?
When I gave it a look, the studies were on the side of split keyboards being the hardware equivalent of snake oil.
But whatever.
And maybe then: are keyboards the best input device in 2026?
Maybe it depends on your individual anatomy, and the sensitivity of it to stresses?
Anyway, the fact alone that you have less bend in the joints of your hands, if used right, seems to avoid all sorts of carpal-tunnel syndrome?
