If you were my physical therapist, I would hear you out. I would understand from what you were telling me that it might be worth trying out a variety of mice, ergonomic or unergonomic, to see if anything at all alleviated my carpal tunnel.You keep insisting there is one standard and that you're going by that one objective standard. I'm telling you as a professional that it's way more complicated than that and there isn't simply a line that says this device is ergonomic and this one isn't. It all depends on the person and context in which it's used which is why this is such a contentious conversation.
People who don't understand this argue like they're talking about different realities... because they ARE different realities.
But when Apple designs a product, they must find out in advance what most people will like. They cannot subscribe to "horses for courses" because everyone is going to get the same keyboard. Therefore, Apple is tasked with finding what makes a keyboard objectively good in the hopes of satisfying as many of their customers as possible. The opening post of this topic noted that Apple has forgotten what made their previous keyboards great since they've lost keyboard travel generation after generation after generation. And this has made typing on them very uncomfortable. Therefore, I said I might replace my Retina MacBook Pro with another similar model. "Horses for courses" is irrelevant when Apple keyboards keep losing key travel generation after generation after generation. There's a history of things getting worse. That's what I was pointing out.
