I think the key might be normal, tapping gently on other wide keys sort of make the same noise, I guess it is more pronounced on the longer space bar. Ripster, would you say that the realforce is more or less tactile than the filco?
I like the easy press and fluid nature but miss the click-threshold of the unicomp. I find myself hitting the space bar by accident because there is very little resistance at the activation point. I don't think blue cherries would make it any better (just noisier.)
I've been lurking for a couple of weeks - have seen good and bad reviews of every keyboard, will probably end up trying them all!
