So someone enlighten me to wood. I thought they were supposed to be soft on your hands?
I think the idea is more for ergonomics than cushiness. Its just placing your wrists in a better spot for ergonomic typing - AFAIK you should be resting your wrists minimally, if at all. Certainly not while typing. Thats just proper form... again AFAIK.
This is actually why I take issue with kinesis advantage keyboards because they seem to encourage the user to rest their wrists all the time. For me I had symptoms in my left wrists (the one not using my mouse) that were RSI or even leading to carpal issues. I have 2 kinesis and the pain went away as soon as I switched to my KBP V60. The pain was from simply resting my wrist on a
gel padLong story short... I think the wooden rests are fine ergonomically and probably suitable from a comfort level if used correctly.
Note: I don't currently own a wrist rest for my 60% but i'm thinking about it.
