It's hard to measure I suppose, I personally started using a Redox Wireless (and now own several split, non-split mechanical keyboards of all variaties). I went from being unable to comfortably type a 1/4 of a page to being able to type an entire page at a time. (I'm a developer, so this is really important to me. I was starting to have RSI/CTS complaints at the start of the year) Here's a study I could find with a quick search: http://ergo.human.cornell.edu/conferences/hfes02/gttalkhfes02.pdf http://ergo.human.cornell.edu/conferences/hfes02/gttalkhfes0... Essentially comfort isn't significantly higher than with a standard keyboard, but there's less discomfort.
