Sometimes switching positions dynamically is less straining than staying in the same (ergonomic) position forever, which is why most ergonomic chairs are about dynamic sitting.
But no amount of dynamic sitting and no ergonomic chair will make the bad influence of sitting go away — this can only be dealt with excercise, breaks and stretching. And every ergonomic chair can be misused. A person with good habits can sit healthy on a rock, a person with bad habits can sit unhealthy on a custom made ergonomic chair.
The same is true for the hands. As a life-long multi-instrumentalist with trained hands and fingers I could totally see someone with a laptop and the right habits ultimatly acting healthier as someone with the wrong habits and the best ergonomic keyboard that exists for them.
And this is the truth: Everything that involves the human motor system is never just about the objects we interact with, but always also to a major degree how we interact with them. My grand-grandmother that worked in her garden with 109 didn't have any ergonomic tools (as they didn't exist), but all the right habits. Habits are always more important than tools.
