A:AnswerThe keyboard is not really ergonomic but if you're wondering if its comfortable it definitely is. The palm rest is a good addition for comfort and the keys depress very easily because of the pink silent microswitches. During extended sessions I don't get any fatigue in my hands. Hope this helps.
