I wish manufacturers of ergonomic keyboards would pay more attention to pointing devices. After all, with modern UIs we have to use the pointer. Having a hand jump to a mouse all the time is, at least, distracting.
Another factor is skeletal symmetry. Reaching for a mouse changes the natural balance of posture. I'm not a doctor, but it cannot be healthy over decades. That's why after many years I'm now using the pointing device with my non-dominant hand most of the time. My dominant hand only takes the mouse when I have to do precise or graphic work. This approach makes my back, neck and shoulders feel better.
And the last major gripe I have with most of ergonomic keyboards is how they misunderstand tactile feedback. They try to make all keys feel the same. Glove80 takes it to the limit with its uniform and flat key shapes and identical switches. I don't think this is helpful. Notice how F and J on most keyboards have bumps. Every key should have a bump, a unique shape, a unique surface texture. I want to subconsciously know I hit the right key.
