Query: Not that ergonomic

This is my third ergonomic keyboard and it's going back as soon as possible. The energy required to depress the keys (esp. the space bar) is considerable enough that it defeats anything gained by the improved wrist position, which any ergonomic (split) keyboard will give. In other words, it might help wrists, but still strains fingers, hands and elbows. My guess is that people rating it highly are mostly comparing it to straight keyboards. I'm buying another Fellowes ergonomic keyboard, which I loved until I spilled liquid in it (d'oh!). Those keys are incredibly easy to press and the back of the keyboard rises slightly so you don't have to reach as far for the top rows. I could type on that one all day. An hour or two with this Microsoft one and my hands are sore, my tennis elbow is flaring up and I'm not happy.
