Earlier this year I finally bought a decent keyboard (Kinesis Advantage). While I was searching for what I wanted, I put together a list of keyboards with some features and have just put it online. Hopefully it can help others in search of a good keyboard. I'm sure the list is incomplete (both in terms of keyboards and listed features). I'll be adding keyboards in the coming days. Feel free to give feedback and suggestions if there are certain things missing.

(e.g. I was thinking about adding filter for cherry mx key color)

I've seen no controlled research that any "ergonomic" keyboard is any better or worse than any other keyboard. Taste-wise, of course, some are clearly better than others, but different people can have different taste.

Is there any science behind this? I don't count "studies" paid for by keyboard makers to be legit --I mean controlled third party studies.

No ISO layout filtering.
