@Demosthenes Wouldn't that ergonomic keyboard have mechanical switches too? I don't really know why, it's just more pleasant to type on compared to the rubber keyboards I was using up until now. I never before wanted to play a typing game, and I really like buttons in general.
In terms of clickity-clackiness, as far as I understand, I got a middle of the road version, I guess even toward the silent. Nobody told me though, that there is also spring ringing upon release, which I find the most pleasant, very musical.
@Demosthenes Hmm, the required distance is very short on this one too, but the allowed distance is longer. I think, this makes it easier to press the key without bottoming it out, so less impact on fingers? They also require less force to press, than my rubber ones, which would resist hard firts, and then just snap down, basically guaranteeing impact (it's a trap!), while the springs resist continuously and lightly.
