Half the time I fail to see what the point of trying not to bottom out at all is. I type faster when I don't go through all the effort of being careful and just pound the keys. That's one of the things that I'm a bit disappointed about when it comes to my browns. I actually type faster on my laptop's scissorswitch keyboard because there is less key travel. I'm not sure what people are talking about with the "shock" from bottoming out... its just a keypress... nothing shocking about it.
If anything, I'm toying with the idea of getting really thick o-rings to purposely reduce key travel and, as such, have a keyboard that would excel at typing that bottoms out.
I'm not saying I disagree with you, but if you're doing typing constantly, apparantly, the extra shock (and it is a shock, albeit a small one) of bottoming out will add up and complicate RSI issues, and finger fatigue.
I notice that by the end of my paper, I sometimes take a break from my unicomp, which helps.
Also, if you're not pushing the key all the way down, then you move your fingers less. Less movement means faster movement (potentially) which equates to better typing speed. It makes some sense, though typing on a red, I still "brush" the keys too much, and have mistakes. I anticipate precision and accuracy to come in time.
Edit: Oh, and it's often a lot quieter.
